[mythtv-users] no fast-forward + no commercia flagging -- frustration
Hi folks, I recently switched my functioning mythtv system (which runs the ubuntu breezy 18.1 packages on a pentium-III system with a hauppauge pvr350 doing all the heavy lifting) over to a new hard drive (old one was too small). I had a little trouble at first getting the filesystems synced, but pretty much thought I had worked out all the kinks until I started watching programs with commercials. Then I found two problems, which I imagine to be mroe or less unrelated, but which combine to make watching tv a whole lot less fun: 1) For some reason no commercials are being flagged. Even if a program is set up with flag -- use all in the database, attempts to skip forward or backward result in a not flagged message flashing on the screen. @) This in itself is a bummer. But there's also a problem with the fast forward button. Sometimes it works fine. But often , pressing the fast forward button (to play at 3x, 5x, or 10x) results in a wierd stall -- the pictures stays almost still, perhaps flickering a bit, and the position indicator will remain stuck at the same moment -- say, 18:32. It might flicker around a bit too, say 18:31, 18:35, 18:32. Meanwhile, the indicated LENGTH of the clip will sluctuate wildly -- so the video will apear to GROW and SHRINK as the picture stays fixed. OFten after doing that for a wile, and in response to some other button press, this wierd behaviour will cease all at once and suddenly the fast worward will work again, at least for a little while. Anyway, it's bizarre and frustrating. I'd very much appreciate any suggestions on e.g. where to look to diagnose the problem further.

The Menu key was named improperly in my lircrc -- lirc sees it as Menu/i and it was called Menu (this is on a pvr-350 w/ a black/silver remote). Now that I'ver enamed it I'm getting the playlist menu when I'm in the watch recordings screen. Thanks everyone! I still don't see a way to move things around in the playlist etc, but this is already a major improvement. while we're on the subject of lircrc... I have a couple of questions about it. I'd really like to map my play button to the play function, which is currently mapped to Ctrl+P in the mythweb bindings interface. But I can't seem to figure out how to write control-P properly in the lircrc file. Ctrl-P, Ctrl+P, and \P, all seem to fail. There are a couple of other control keys in the standard keybindings; I'd like to be able to map them as well, if possible. in addition... I've had to reboot several times lately (mostly because of a buggy power cable, I think), so I've noticed something I mightn't otherwise. When I boot up, I autologin the mythtv user from gdm, which runs a minimal wm starts mythfrontend directly. The first time I do this after booting, mythfrontend doesn't seem to receive any keypresses from the remote (though I can check with irw that the remote is in fact sending, and lircd is up and receiving). If I /etc/init.d/gdm restart then things seem to work fine again. Anyone know what the deal is with that? Do I need to modify my init scripts somehow perhaps? thanks again, matt --- Matt Price [EMAIL PROTECTED] History Department, University of Toronto (416) 978-2094 ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
[mythtv-users] playslist for recorded tv?
in the watch recordings menu, it's possible to select a recorded program, push the right button, and then select add to playlist. does anyone know a) what this playlist is? -- I've never seen it actually activated. b) whether there's some way to manipulate the playlist more directly (e.g. change the order in which shows are viewed, etc c) escape into the playlist while viewing, etc... The playlist would be very useful for me as my kids watch shows that are 12-19 minutes long -- I'dl ike to set them up with an hour of TV in such a way that I don't have to run upstairs to the TV every 10 minutes. However, I haven't been able to use the playlist in a useful way at all. And while the docs talk about playlists for mythmusic, I don't see any such discussion for straight mythtv. failing a builtin playlist generator, anyone have any ideas for command-line playlist generation? thanks, matt --- Matt Price [EMAIL PROTECTED] History Department, University of Toronto (416) 978-2094 ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
[mythtv-users] cut commercials only, no transcoding
Hi, I need to save some space on my l'ill old drive but I am running a pretty slow system (PIII-450, with a PVR350 doing all the heavy lifting). can't play dvd's on this system, for instance. So I don't think that transcoding will work well with this CPU.

And then, run commercial_cut to remove the commercial. I do this all from a single script without actually looking/editing the commercial points. I trust mythcommflag is doing very good job and I do detect almost all the commercials. Only one time, it deleted everything of the Lost episode after the first commercial. this sounds excellent. would you mind posting the script? Just as a reference point... I find the commerc ial flagging is great on shows that actually have commercials. On shows recorded from public broadcasters it sometimes flags parts of the program itself. not sure what's doing that... anyway thanks. matt On 1/13/06, Matt Price [EMAIL PROTECTED] wrote: Hi, I need to save some space on my l'ill old drive but I am running a pretty slow system (PIII-450, with a PVR350 doing all the heavy lifting). can't play dvd's on this system, for instance.

Are there any tweaks I can apply to speed up the funcitoning of the gui? The Prescaling Images IS what's done to speed up the GUI. If we didn't do that (And it's cached for following runs, so it shouldn't take near so long the second time) then we'd have to re-scale the images every time you change screen. I see. As you suggested I built a slightly less complex theme. Since I know nothing about myth or xml, I just deleted al lthe buttons from theme.xml in the default /GANT theme, which produced a noticable speedup both in the initial startup and in the screen redraws when flipping between options. There's still a short delay between rescaling images and the appearance of the main menu -- not sure what causes that, as it's not reported in the onscreen messages. But all in all this seems a pretty good solution. As the besic premise is that the Myth box is kept running 24/7, you should only have to see the Prescaling Images prompt once in a blue moon. eventuallyv I do want to go to 24/7 usage -- though I was htinkinga bout giving the system a break a few hours a day to save electricity. failing that, it would be nice to be able to greatly diminish power consumption when system is idle by spinning down the drive, reducing cpu activity, etc. Since my system is noisier than I'd like that'd have multiple bonuses. I figure this must be a trick other people have tried -- what techniques do folks use? Another suggestion would be to make sure that the 350 is in the highest PCI slot you can, not a shared PCI/ISA slot, as that will enable the card to use BusMastering, which will speed things up some. Also make sure you have enabled DMA transfers on your hard-drive with HDParm (If they're supported on your motherboard). DMA is on, but I will look in to the slot -- I think I may have the card in the scond slot, not the first, and can easily change that. Unfortunately, as it's only a PIII system you have, manipulating fullscreen graphics will be slow. The only thing I could recommend is to perhaps change the rendering method, or build yourself a Theme that has only basic colours in (No fancy images to scale and resize = performance boost). That's about it, though.

[mythtv-users] color adjustments to pvr-350
hi folks, myth is running great, but the recordings look funny when played on my pvr-350 (kinda green and a little washed out). Tried copying one of the files to another computer and playing via mplayer on a normal (crt monitor) xsession, and the color distortion doesn't appear. It also seems to me that dd if=/dev/video0 of=/dev/video16 that is, playing the pvr-350's video-in directly to its video-out, also doesn't give the color distortion (though I have to experiment with that more extensively -- it's difficult b/c it won't work when mythfrontend is running). can't find documentation re: how to adjust colorsi n myth or using ivtv -- can anyone help? anyone seen this problem before? thanks, matt ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

hi jeff, can't find documentation re: how to adjust colorsi n myth or using ivtv -- can anyone help? anyone seen this problem before? yes, I've definitely seen this problem before, to fix it you need to change some registers in the PVR350: http://www.gossamer-threads.com/lists/mythtv/users/164931?search_string=green%20350;#164931 depending on which revision of the 350 you have, the registers are different, but those are the ones I reverse-engineered. ok, great, thanks. looks a ibt hairy to me, but I will give it a go. esp with regard to the first of the registers you discuss in this thread: if I don't want to mess with the screen position (yet) do I just recet the last digit of the register?

[mythtv-users] starting X on tv-out from Hauppauge pvr-350
hello folks, apologies for the cross-posting, I'm not exctly sure where this question belongs. I am trying to get a mythtv setup working under ubuntu breezy, using a hauppauge pvr-350 as my capture card; other hardware is old generic dell pentium-III -- may well move to something more substantial if I can get the system working otherwise. Following instructions from varioys places (http://www.willmer.com/kb/2005/04/x-out-on-a-pvr-350/, http://www.quietglow.com/docs/ubuntumythtv.html especially) I have had moderate success: ivtv modules load fine, I can watch tv on a monitor using mythtv, and using dd if=/dev/video0 of=/dev/video16 bs=64k I can see television on the tv using the pvr-350's tv-out. so all of that's gret. However I would like to use this system exclusively from the tv, andi n order to do that I need to set up an xserver on the tv. I feel like I'm getting close, having conquered several problems already, but I'ver run up against something I've never understood, related to the framebuffer. I have the following in xorg.conf: Section Device Identifier Hauppauge PVR350 Driver ivtvdev Option fbdev /dev/fb1 # Option fbdev /dev/fb0 BusID 0:13:0 # this is the PCI ID you got earlier. EndSection Section Screen Identifier TV Device Hauppauge PVR350 Monitor NTSC Monitor DefaultDepth 24 DefaultFbbpp 32 Subsection Display Depth 24 FbBpp 32 EndSubsection EndSection --- obviously lots of stuff is snipped out, and you can see I'm alternating on t he /dev/fb line (/dev/fb0 vs //dev/fb1) the problems with xorg seem to relate to this line. Everythign works fine -- drivers load etc -- until this point: (II) Loading /usr/X11R6/lib/modules/input/mouse_drv.o (II) Module mouse: vendor=X.Org Foundation compiled for 6.8.2, module version = 1.0.0 Module class: X.Org XInput Driver ABI class: X.Org XInput driver, version 0.4 (II) IVTVDEV_TST: driver for framebuffer: PVR-350 (II) Primary Device is: PCI 01:00:0 (--) Chipset PVR-350 found (EE) open /dev/fb1: No such file or directory (EE) Screen 0 deleted because of no matching config section. (II) UnloadModule: ivtvdev (EE) Device(s) detected, but none match those in the config file. Fatal server error: no screens found I notice that the Primary Device listed here is my onboard video card, not the pvr-350; not sure why that information comes up, and also not sure it's relevant. Also, I checked for /dev/fb1 and in fact there is no such file. so I tried changing that line to /dev/fb0, which does exist, and got this instead: (II) IVTVDEV_TST: driver for framebuffer: PVR-350 (II) Primary Device is: PCI 01:00:0 (--) Chipset PVR-350 found (EE) ivtvHWProvbe failed to do IVTVFB_IOCTL_GET_STATE for device /dev/fb0 (EE) Screen 0 deleted because of no matching config section.
