The DVD's I'm burning using the new mythburn-ui in R5B7 all seem to have sound drop-outs with lossless transcoded files. I should point out that the transcoded file itself plays fine on the hard drive. I think it has to do with audio discontinuities at places where commercials used to be (before being cut out). Once the sound drops out in a recording, it's gone for the remainder of it. The problems are very similar to those described in the troubleshooting section of the "MythTVBurn_Scripts_HowTo" in knoppmythwiki.org. I've tried all of those suggestions, plus some others I found here in the forums, but none of them have worked. I've included portions of the mythburn.log file below. By the way, I'm using a PVR-500 and am recording at 720x480. Although I updated mythburn using cvs today, I was having the same problem before and after the update. Note particularly the length of the video (43 minutes) and audio (23 minutes) portions of the recording. This is exactly where the sound stops in the burned DVD.



lots of stuff deleted ...



Any ideas??

As you have discovered the mpeg2 to mpeg2 stuff in mythtranscode isn't yet perfected It might be worth posting this on the mythtv dev list to see what Geoffrey Hausheer makes of it.

In the mean time if you know you are going to burn a recording to DVD it is probably better not to use mythtranscode to cut commercials and let mythburn cut them out instead using ProjectX which seems to work better.

Do you by any chance still have the original uncut recording? It would be interesting to let mythburn do the commercial cutting and see if that works

Thanks for heads up there, I was experiencing a slightly different problem with lossless transcoding but it's good to know of this potential one as well.

projectX does seem to do a really good job at handling glitches in recorded material, I have experienced some in the lossless decoding that I never used to have after recording to DVD via mythburn/projectX.

No, I don't have the original. I didn't have that feature enabled when I did the transcoding. I neglected to try burning a DVD the "old-fashioned" way - letting mythburn use the cutlist - because on a previous fresh install of R5B7, mythburn-ui did not work and mythburn through mythweb didn't apply the cutlist. Since mythburn-ui seems to be working fine this time around, I'm assuming that it will apply the cutlist properly, while mythburn (through mythweb) is still not fully functional(?)

Hopefully the problem with the web interface not always telling the script to apply the cut list should be fixed in cvs now. It usually takes about 5 hours before the public cvs servers are updated so leave it a while before you do a cvs up.

I finally had a chance to get back to my system today. I updated mythburn using cvs:

As root -
# cd /myth/mythburn
# cvs update
# ./install.sh

Although the cutlist seems to be applied just fine, unfortunately I can now not get either a burned DVD or the VIDEO_TS folder to play properly using xine. The initial menu screen comes up, but when I try to select one of the two programs on the DVD (or VIDEO_TS), xine crashes back out to MythTV. I selected the "create submenus" option when I set up the burn parameters. I haven't checked to see whether unchecking that option would "solve" the problem.

Another couple of points regarding the mythburn web interface: if I try to create the DVD through it, I also have the same problem as described above, and in addition, the images on the initial menu are the wrong aspect ratio. Instead of the typical 4:3 NTSC, it's some stretched HDTV format. Also the menu selection border images don't appear on the web page - just the image names, but the selected border seems to be properly applied (at least in the initial DVD menu).

I have also experienced this audio cut out with lossless transcoded files...but not all of them. I was also wondering how I could get Mythburn to cut the commercials for me using projectX since there is no option in the Mythweb UI for this option, and people said it works better
