At present, I am still running R5F1 - with the Schedules Direct modification that Cecil provided to us in the thread http://www.mysettopbox.tv/phpBB2/viewtopic.php?t=16178

After that modification, everything seemed to work fine. Then, a few nights ago, I wanted to burn a DVD using MythArchive and it screwed it up. (Mytharchive was working fine before the SVN update I mentioned.) The program I wanted to burn was 1.6GB in size. The DVD output only had a 43MB file on it! I looked in the /myth/tmp/work folder and the dvd file structure stored there also had the same 43MB video file. So it was not a burning error, but a MythArchive error in creating the DVD video sturcture.

Has anyone else seen this problem with SVN code breaking your MythArchive?
Would it fix MythArchive to do the SVN code download/recompile again today with the thought that the SVN code of today is different than the SVN code of 3 weeks ago?

Insight appreciated,
Eric

Of note, I just tried another DVD creation and chose a different video file. This time, it worked - with no changes to the system.

So, this makes me wonder if there was some mpeg video errors in the source video file that failed to produce a complete DVD.

Sound like a reasonable theory based on the evidence?

Wouldn't surprise me, particularly if it's HDTV. I had a heck of a time getting HDTV to work every time with mytharchive (and the tools it uses by default).

An easy way to check would be to redo the file (maybe with just create iso instead of burn dvd checked to save you a coaster) and see if any of the files created in the /myth/tmp/work/#/ directory is cut off.

Also, you could try looking in the /myth/tmp/logs directory at progress.log or mytharchive.log (one of them has more detail than the other) files and see if any particular errors pop up.

Yes, it is a DTV recording (digital tv via the HD-3000 card) but it was a standard definition broadcast from our standard definition PBS DTV channel. I recorded the standard definition broadcast so I could share the program with HD-impared friends.

I tried MythArchive twice on that recording and both times it produced a full length video file in the /myth/tmp/work/# directory but a truncated file in the /myth/tmp/work/dvd directory.

I took the same recording and transferred over to the Windoze machine and used Ulead DVD Movie Factory to make a dvd - that worked fine.

I'll see if there is any leftovers from the failed dvd creation attempt in the /myth/tmp/logs directory.

Well, just as a side note, since you're encoding the content into DVD format anyways, you can use HD sourced content for your HD-impaired friends.

There should be multiple files in the work/# directory. The stream* files are the demuxed audio and video streams used to create the DVD video file. Playing them with xine or mplayer might shed some light if the video file is truncated.

Really? MythArchive will transcode a recorded HDTV file down to a standard definition file and burn a dvd of it right out of the box? (meaning there are no extra scripts that I have to write and run) :o

Well, the reason is that DVD's aren't HD themselves.

Any DVD-Video mytharchive creates follows the standards. The biggest component to mytharchive and the tools it using (IMHO) is to translate whatever format video you give it into the very strict formats allowed by the DVD-Video standards.

Correct. Video DVDs are SD by definition.
I simply was not aware that MythArchive had the ability to transcode HDTV down to SD. I'll test it soon!

At present, I use Roxio 8 do my HDTV to SD transcoding for DVD creation. The output SD video isn't without problems, but in my experience, it produces the best looking SD output from an HD source file.

A lot of people have HD->DVD working fine out of the box.

I had to take these steps personally:

I just re-did the experiment. The file failed to be made into a dvd again.

It looks like the DVDauthor program had a hard time with the file and quit about 43MB into multiplexing it. DVDAuthor version 0.6.13. isn't as robust as I thought.

I just tried a test of burning an HDTV program to DVD using MythArchive. It "terminates" during the HDTV to NTSC file conversion. My system is still at R5F1. So, I guess it doesn't work in R5F1. See the progress.log file:

It's not DVDAuthor, it's mplex that's having the problems, and that's because the steams passed into have issues it can't resolve. As I said earlier, the tools used by mytharchive do a good job, but aren't perfect. Particularly since the recorded files passed in generally have a lot of problems with them.

You can try the steps I pointed to earlier that I did which have so far (fingers crossed) been very successful for me. We'll have to wait for the tools to get better (or if you have the time you can help out).
