My the way, is my set up going to break EVERY time there is an incremental release (where I have it on one system but not on the other)? Why isn't this backwards compatible to the previous release?

[mythtv-users] Network protocol problem: what does this mean?
I have a wierd problem. I have mythtv set up and working OK. Now I want to use another machine as a front end, in a remote location. I set up mythtv on that frontend, entered the relevant IP address... and it tells me this: The server uses network protocol version 14, but this client only understands version 15. Make sure you are running compatible versions of the backend and frontend. Have any of you seen this? What is it referring to. I think that both versions of mythtv are 0.18. I think the frontend version of mySQL is newer but would that matter? What IS the "network protocol" version 14 or 15 that it is referring to and what can I do about it. The backend is running ubuntu 5.04 amd64. The frontend machine is running debian sid amd64. The former was a breeze to install, while the latter was a total bitch. I couldn't get mythtv to install vi apt-get (turns out it is the 32 bit version), it wouldn't install from deb-src, and I couldn't get it to install from the tar ball. (Later found out I have to change the version of gcc for this.) but someone DID point me to a new 64bit deb file here: deb http://pure64.org/debian ./ Got that installed, then ran into set up problems. I eventually tracked that down to a problem with mySQL. I use version 4.1 which uses different password authentication. After telling it to use the old-style, mythtv got set up OK. Now if only I can figure out this "network protocol" version thing maybe my setup will be complete.

Like Michael I have had no luck with automatic transcoding (on a fairly new mythtv install). That "automatically transcode" box IS checked, but there is no transcoding and no mention of transcoding in mythbackend.log.

Re: [mythtv-users] Auto transcode and commercial cutting not happening
Thanks everyone for all the help so far. Hope I can get this figured out.

I used ffmpeg to manually transcode a couple programs. Is there a way to skip commercials with ffmpeg? (I don't think so.) I tried nuvexport but it stopped with an error and it was easier to use what I know (ffmpeg) rather than trying to figure out what is wrong with nuvexport. Anyway, I thought that mythtv was supposed to be doing this (transcode and cut commercials) automatically after it finished recording. Am I wrong about this? Does everyone have to run nuvexport manually?

I have a file that has already been recorded and want to transcode that. I don't need to tell it a channel or starttime, but rather an input file. And it fails.

If I understand things correctly, mythtv calls mythtranscode after it finishes recording. I tried using mythtranscode from the command line to see what is happening and it failed: %mythtranscode -i 1058_20050921163000_2005092117.nuv -f foo.avi Stream: 0 Type: 0 Stream: 1 Type: 1 Input #0, mpeg, from '1058_20050921163000_2005092117.nuv': Stream #0.0: Video: mpeg2video, 480x480, 29.97 fps, 6000 kb/s Stream #0.1: Audio: mp2, 48000 Hz, stereo, 384 kb/s mythtranscode: mpeg2trans.cpp:668: bool MPEG2trans::process_video(AVPacket*, bool): Assertion `0' failed.

[mythtv-users] Auto transcode and commercial cutting not happening
HI, I am not sure if I have overlooked something or it is just ignorance, but mythtv doesn't seem to be either flagging commercials or doing automatic transcoding. On the mythfrontend settings I have the appropriate checkboxes checked to allow for automatic transcoding and commercial detection. On mythweb when I set it to record a program the checkboxes for "Auto-flag commercials" is checked. However, the shows are not transcoded (they are left in .nuv format), and the commercials are still present. But then it HAS to be transcoded in order for commercials to be cut, right? But Mythweb also has "has cutlist: no" ... and I thought this SHOULD be "yes" since it is set to auto-flag commercials. Have I misunderstood this? Can anyone show me where I might have gone wrong here? Craig ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
[mythtv-users] mythTV settings from the command line?
Hi, I recently set up a mythTV backend using Ubuntu 5 AMD64, and it seems to be working OK. Bit of background - the backend is in Canada. I am on the other side of the world in Japan, and I want to be able to see Canadian hockey and maybe some local programming. The problem is that I can't use mythTV via the frontend (since I don't have physical access to the machine) and I would like to manipulate it via the command line if possible. I have mythweb set up, but it only allows me to schedule recordings and not alter settings. (Note - I DID set up a vnc server, and it worked when I was home recently, but I can't get in now for some reason, so that isn't an option.) Does anyone else do this kind of thing? I can't find any information online about how mythtv is set up behind the scenes. I had assumed that settings would be stored in some config files but I can't find any. ARE there config files or not? I have come to the conclusion that all of the settings must be stored in a mySQL database. Is that correct? I checked out the mythconverg database using phpmyadmin last night, but don't yet have a good handle on it. Specifically, I am trying to figure out how to change settings concerned with commercial detection and deletion, automatic transcoding after recording and perhaps video card settings. (I have a Hauppauge PVR-150 and thought I read somewhere it could record directly to MPEG4 rather than MPEG2.) Also, my aspect ration seems to be off. The picture is tall, but narrow relative to a normal TV screen. Can anyone tell me how to view and adjust these settings without using mythtv-frontend?

[mythtv-users] CPU recommendation instead of EPIA?
I am planning on building a mythTV box and need a recommendation regarding CPU. My original plan was to build around a mini-itx EPIA system (EPIA M-1 or M-12000). However, after reading through this board (and having a previous question answered) I think that I should consider another system. I am concerned about transcoding performance with the EPIA CPUs. I plan to use this box only as a back end to record TV and transcode. I understand that with EPIA CPUs performance for transcoding is terrible. What kind of CPU would you recommend? I don't want to spend too much (otherwise, I wouldn't ask here - I would just go buy the lastest from AMD or Intel). Also, I would prefer to build a system that is: - less power-hungry (uses less electricity) - is fairly quiet - has a smaller form factor This is why I originally planned a mini-itx system. I know it is a subjective question, but what kind of (AMD / INTEL) CPU provides the 'sweet spot' for price vs. performance (vis. a vis. transcoding)?

Re: [mythtv-users] Via M10000
I too am interested in the Epia M1000. Is anyone here using this, and can you answer a couple questions? A bit of background: I want to build a box to record and transcode TV ONLY. I don't care about playback etc. I will move the files on my network to another machine for playback so none of those related issues are relevant. The reason I am interested in the M1000 is that I want a very small form factor and I want a silent or almost-silent box. (I am thinking about using the Otonashi case with a heatpipe rather than CPU fan.) What I am wondering is how the Epia performs at transcoding. I know this can take up a lot of CPU power. How long does it take to (remove commercials and)transcode an hour of video down to something smaller? Can anyone recommend any other small form factor, relatively cool CPU / motherboard for my project?
