I would suspect that the specs were written such that this sort of organisational detail is up to the network that runs the multiplex(es). Whilst it's a stated wish that Myth should be able to handle multiple channels simultaneously from a single multiplex, I don't think anybody is actively working on this feature (they can correct me if i'm wrong!).

Not all muxes are transmitted with the same power. There's a website somewhere that tells you the power of each mux for each transmitter (should be linked from the freeview website). 2. The sensitivity of your aerial is not constant across all frequencies. You can buy aerials that give you excellent reception for certain frequency bands (you'll need to figure out which one is best or your transmitter) or you can get a 'wideband' aerial that will give you average reception over a frequency range that should cover any transmitter (this is what most standard retailers will sell you). Chances are that what you are reporting is due to '2' above. The 'bad' mux is almost certainly on the highest or lowest frequency of the six muxes for your transmitter, and you'll almost certainly be using a 'wideband' aerial.

Just a quick follow-up to my earlier post. You can see the gain for different aerial groups on the follwoing graph http://www.wrightsaerials.tv/Articles/img/fig%201, Obviously, higher gain is better. The power of the different muxes is given on this page: http://.dtt-tx-info.org/change_tx.htm As you can see, muxes C and D are transmitted at half power compared to the rest. And since mux D is at the highest frequency i'd guess that the one you're having problems with, right? (Mux D shows TMF, The Hits, Ftn, etc).

If your TV has a SCART socket then i'd highly recommend soldering up your own VGA to SCART convertor. Then you can use an interlaced modeline to output a legal PAL/NTSC signal from vid card (i'm using an Nvidia MX440).

Run mythtvsetup then choose Input -- Select input connection -- change Starting channel in the setup page. The problem with this is that it gets reset each time you change the channel to the currently tuned one. As my original positing said, i've already tried this and it doesn't appear to make a difference to the channel that's tuned when the card is idle. This setting only seems to affect which channel is tuned on next entry to livetv. This seems to be related to the channel crawling feature that's been muted, i.e the DVB code would when mythtv was idle tune to each of the channels and attempt to update the EPG. However it's not bubbled to the top of the list yet. Indeed it does seem related, although i'm only looking for the basic functionality of being able to specify a single channel that will be used when the card is idle. I think the consensus seems to be that this currently requires a manual database tweak rather than being configurable through any GUI (would be nuice if you could confirm this, I was half expecting to need to change a hard-coded value in the source). If there is a work-around then i'll happily use that until the channel crawling functionality becomes a reality.

Secondly, I only appear to be getting guide data for the mux/transport i'm tuned to, even though in the UK (Freeview) the guide data for all muxes are sent on every mux, is this correct / expected? Not quite true, some mux's are better than others for EIT data. mux one seems to have everything most of the time. That's what I expected. I left it on live-tv on BBC1 for half an hour, even then I had no guide data for (example) Channel-5. Flicking over to channel 5 manually resulted in guide data being built up for that channel. The result is that i'd have to sit there watching a channel for each mux in turn to fully update the guide, not ideal! Taylor was considering doing this auto magically, but it shouldn't be needed in the UK. Agreed, I didn't think it should be required. Previously i've been using tv_grab_dvb with great success to get my guide data (the system has no internet connection), is it possible to still use this tool until the wrinkles with the internal guide grabber have been sorted? ... or have the database changes made current versions of tv_grab_dvb unusable? It should be ok, but you need to switch of the OTA guide setting and fill in the xmltvid. Ok, so it's possible, but a setup hassle. Thanks for the response, i'll play about some more and see if I can sort this out. Steve ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
Re: [mythtv-users] Is Mplayer going away? Anyone seen their WWW site recently?
Sorry, but as a patent attorney I assume she gets a salary? Makes a profit for the company she works for? She therefore has a vested interest, and that would make her biased, as her livelyhood depends on the need for patent attorneys. Contrary to popular belief and propaganda, patent attorneys are people just like you and me, many of them therefore have a conscience and a degree of professional integrity. It may surprise you to learn that most of them are interested in encouraging innovation, as indeed is the European Patent Office (who, if you want to did deeper, you will discover they often find in favour of 'the little guy' as a matter of principle and fairness over and above the strict interpretation of the law). Neither the EPO nor european patent attorneys want a system like that being run in America, fact. Great, so we define the specificity of a law after it is created in the all out land grab that ensues. Patent law is based on case precedent, welcome to reality. Your last sentence is nonsensical. One of the EPO's public statements is that this is intended to harmonise European patent law. Clearly you misread it then, as I said, the intention is to stop certain countries in the EU from using loopholes to get software patents (which the EPO does not want). Stopping these countries would be described as harmonisation to me. Then why won't they explicitly exclude pure software patents in unequivocal terms? The language is convoluted, but the upshot is that as long as software has a technical effect it can be patented. Like to explain technical effect for me. People are still trying to get clarification on this. As I said, european patent law is based on precedent. The limits of 'Technical effect' have been determined through case history, this is why you need to talk somebody who's well informed in that area, i.e. a patent attorney. MythWeb and MythBrowser: BT have a USP on the hyperlink. Well, no. They tried to play that card but failed. MythMusic MythStream: Franhoefer et al have patents on MP3 encoding decoding. Not in the EU they don't. We don't have software patents remember. They have copyright on their own software implementation, nothing more. MythPhone: Voice compression codecs. MythTV: The ability to pause and buffer TV, then catch up. MythNews: I think RSS is based on RDF which is covered by an EP. Samba file shares: Good ol' MS have patents on CIFS. WishTV: Might be covered if the automated suggestions from other viewers gets developed. Ditto, ditto, ditto. This might be different in America, but their patent system is fundamentally different. Feel free to try and convince me that big business is the one to structure the legal framework we all have to live with, but I'm a tough sell. I'm not trying to do that, and that's not the way it works in the EPO. Who will determine the rulings are the EPO judges who have a very good track record for upholding common-sense, fairness and protection of 'the little guy'. I'm not trying to say this situation is perfect, it's clearly not. Do try to understand that software patents are starting to be forced through in the EU right now due to inconsistencies in laws that were never intended to cover this subject! The EPO (like you) wants to stop that from happening, like it or not this is the basis for the CIID. ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
Re: [mythtv-users] Is Mplayer going away? Anyone seen their WWW site recently?
No offence, but DUH!!! Of course a patent attorney is going to say that this law is all hunky-dory, it's his future bread and butter!!! Well, actually no. Her firm does not take work of this kind and as such is unbiassed in this matter. On the other hand they are fully informed as to what is going on, and why. And yes, I have looked at both sides of the argument, read Groklaw, etc, have you? The ambiguous wording of the CIID opens the back door for pure software patents, and there is a whole saga going on with the European Parliament at loggerheads with the European Commission over amendments and procedure. The CIID may well be ambiguously worded, but that's no different to any other bit of law. The exisitance of a truely unambiguous piece of law is a myth. It's final meaning will only be defined following a set of test cases. The European Patent Office has no intention of changing how software is currently treated, test cases will quickly confirm this position. I suggest you head over to www.groklaw.net for a thorough and informative view of what's going on. It may (debatably) be biased the other way, but at least you'd have both sides of the argument. Really! Would you ask a fox to guard the chicken coop? You're right, Groklaw is biased the other way. Personally I consider a patent attorney with no personnel or financial involvement in this area to be about as unbiassed and well informed as you'll find. Wrong! Tell _no_ material impact to all the small and medium business (the ones that usually drive innovation) that will be driven out of business by this law. Innovation through litigation? Don't believe everything you read at Groklaw. The purpose of this directive is to _stop_ some countries in the EU that have been pushing software patents through the back doors and loop holes that currently exist.

Re: [mythtv-users] How I got great quality TV-out on my nVidia MX4000
Someone else here wrote, that RGB is *too* sharp for MPEG2 video, meaning that you see the artifacts then. Thomas I expect it depends on where you got the MPEG2 video from. Using a VGA - SCART converter in the UK with DVB-T I get an amazing image which rarely has any visible artifacts. But then the DVB-T MPEG stream was encoded with the intention of it being displayed on a TV with RGB inputs, so that's hardly surprising. If your MPEG stream is being encoded by a PVR-xxx card then it may well be a completely different story, I doubt the quality of the encoding is comparable.

Re: [mythtv-users] How I got great quality TV-out on my nVidia MX4000
Of course, the way to get 'optimal' TV-out from your Nvidia (or other) card is not to use it's TV-out facilities at all and build a VGA - SCART converter for SDTVs (see http://www.sput.nl/hardware/tv-x.html for example). This is only true of home-built converters, commercial converters perform scan conversion which lowers the image quality. Then (with the correct modeline) you _can_ just send the originally broadcast, interlaced, stream straight to your TV. You are also keeping the RGB signals seperate, not mixing them all together as you do with S-video. No deinterlacing or scaling is required so you're not losing image quality their either, or wasting CPU power. Oh course, this does rely on you being able to capture the original interlaced signal (i'm capturing a DVB MPEG stream, no encoder required). If you're encoding hardware has already thrown that information away and mixed the odd/even fields then you've already lost the image quality. Using a VGA - SCART converter in this case would still give you better colour definition / sharpness, and if you're encoding at the native resolution then no scaling is required. I've built one of these and the result is _much_ better than the TV-out from by Nvidia card. The image quality is even higher than from my Sony DVB set-top-box.

I had a look around at the time I was first comptemplating this route but wasn't able to find any equivalent system for sale commercially. The reason being that there is a possibility (well, a theoretical one anyway) that you can damage your TV through use of out-of-spec modelines, therefore noboddy sells these commercially. I find that my TV simply won't lock onto the sync signals if you send an out-of-spec signal. You just end up looking at colourful garbage if you're modeline is wrong (or when you're not in X, i.e. booting). I've yet to hear of any cases where TVs have been damaged in this way.

Re: [mythtv-users] Tearing in playback
You don't state what your video card is, but I had a similar problem using an MX440 with a VGA - SCART adaptor. The MX440 has two video out ports (I was using one to my TV thought the VGA - SCART and one to a standard monitor), it tunrs out the refresh of the two displays were not in sync (even though they could be, both were are at 50Hz) and the driver arbitrarily chose which refresh signal to report back to X / Myth / Xine / whatever else might be interested. It just happened that Myth was syncing to the monitor refresh and not the TV refresh, thereby tearing the image on the TV. If you have a similar setup then try disabling all over video outputs except the TV and see if that fixes things. If not, then try running Myth with verbose messages enabled and see which sync method it's actually using. If you don't have an Nvidia card then you probably want to make sure you're using the OpenGL sync method.

Re: [mythtv-users] TV Output
The modeline I supplied is for use with homebrew VGA to SCART converters, these only work by getting the video card to output a signal which is within the spec expected by your TV. Commercial converters (such the Key Digital converter) are scan converters, these scale and interpolate whatever VGA signal you send them into a normal TV signal. As such it really shouldn't matter what resolution you send them (well, they'll work but some resolutions will produce better results I suppose), check to manual to see what the valid modes are. Since you're using a scan converter you won't be getting as high a quality image as is possible from a homebrew converter, this is because of the scaling and interpolation it's performing. Steve I don't suppose you have a simliar spec for a progressive PAL image do you? (I have the Key Digital VGA to Component adapter) I generated one based off a Powerstrip mode to get 1024x576 which gives an awesome picture, but I'm not sure whether it's entirely in spec as the TV's input identifier is flashing in the corner, which apart from being really annoying probably means that the signal is not entirely in spec.

This has been fixed in CVS for a while now, I don't remember the exact date. If you're getting good guide data but always seeing the same error code then this is probably what's going on. Either upgrade to CVS to get the correct result status or just ignore it until 0.17 turns up, it's harmless.

Re: [mythtv-users] TV Output
Glad to hear you're making progress. The image really should be centred, the signal is as close to spec as possible. Are you sure that you haven't set Myth to recentre the image? You might have done that for you're previous S-video out and haven't reverted it... Assuming that's not the case you have two options (1) use Myth config options to offset the display X and Y to centre the picture or (2) mess with the modeline slightly to alter the front/back porch lengths for both horizontal and vertical, just make sure you keep the sync widths the same. Option 1 would fix Myth put would still mean that other programs, e.g. Mplayer/Xine/Ogle are off-centre. Option 2 requires a bit of experimentation put would result in all programs being centred.

Re: [mythtv-users] TV Output
The strange thing now is that already video playback is OK the bottom and right of the menus seems to be chopped off. I have both the GUI and the default playback size set for 720x576 at the moment. That's to be expected. You'll need to setup Myth to scale the GUI such that it fits on your particular TV, this is take into account how much you TV overscans the image. The amount of overscan varies from TV to TV, and depending on how well alligned the gun is on your particular 'set may not be equal top/bottom left/right. It's always going to a manual tuning exercise to get it looking just right your own 'set. The other wierd thing is that the OSD text doesn't look right at all. It was fine with the S-Video corruption but now looks like is being subject to some horrid scaling that is causing bits of it to be lost or something. Odd, not sure about this one. Personally the OSD looks fine on my system, maybe its to do with the font you're using? Hopefully somebody else can try and explain this...

Re: [mythtv-users] TV Output
I have a very similar setup, DVB-T to a widescreen TV via a Geforce MX. I agree, the native TV out of the vid card is a little disappointing. Instead, quite a few people on this list (me included) are using home-built VGA - SCART converters. Don't bother trying to buy one of these since they will all of the retail versions use scan conversion which really lowers the quality.

Re: [mythtv-users] TV Output
Sure, damage to the TV is possible, but not very likely! Just make sure that you wire it all up correctly, it's a very simple circuit. Until you're into X you'll be outputting a signal well outside of PAL/NTSC spec (I believe the horizontal rate of your graphics card is roughly double that of PAL/NTSC). What you'll most likely see is two squashed images side-by-side on your TV before you get to X, or maybe just garbage is the TV fails to sync to anything. Again, it's _possible_ this could damage your TV, but i've never heard of this happening. If it's a modern TV it may not display anything and just stay blank until it receives an in-spec signal, YMMV.
