Hi, <br><br>I found a couple of bugs, one is in the file, silence.mp2, which as you may imagine is silence but for 5 seconds, its encoded at compact disk friendly 44.100Khz, not at DVD friendly 48000Khz. I re-made mine with these commands:
<br><br>arecord -f dat -twav -d 5 /tmp/silence.wav<br>mp2enc -r 48000 -o /tmp/silence.mp2 </tmp/silence.wav<br>su - (password)<br>cp /tmp/silence.mp2 /usr/local/share/mythtv/mytharvice/music/silence.mp2<br><br>It appeared to be causing errors in the
mythburn.log when replexing the video, these may of been harmless, but still a bug.<br><br>The other bug is more serious at least for me and will account for a proportion of the dvd's with no sound issues. The introductorary videos, in particular file pal_mythlogo_intro.mpg has AC3 sound, unlike the other two 2 pal intro's which have mp2 sound. When the final dvd is remultiplexed together the AC3 soundtrack from the intro video is made into the primary audio track on the dvd. The remaining audio on the dvd, for me in the UK is MP2 from the DVB-T telly, gets encoded as the 2nd audio track on the dvd. This results in a dvd that appears to have no sound after the intro videom, unless you know to switch soundtrack. I suspect that its non-standard to mix both types of audio coding on one dvd but I don't know for sure, perhaps its my mplex or perhaps there is another way around this. My quick fix was to copy pal_mythtv_into.mpg over the top of pal_mythlogo-
intro.mpg.<br><br>I haven't read that these bugs have already been found, then again I might of missed them on the lists, i'm not up to date with the svn, about a week adrift.<br><br>regards<br>dave s<br><br><br>

<br><br>Any chance you can transcode some of your recordings and see if you have to switch the audio track afterwards??<br><br>Thanks<br><span class="sg"><br>Roy<br>

There are no little voices describing the telly pictures 'Nora quickly poured the tea' or whatever.
<br><br>Roy, i've never used the transcoding facility, I used to use projectX to burn to dvd and used avidemux2 to do the editing, this seems to be better. So I wouldn't know where to start but I may have a go. Let me ask you something, you have the same problem with mytharchive? Look at the
mythburn.log file from a failed (quiet) disk, do you have a section that looks like this:<br><br>...<br>INFO: Audio ch 0 format: mp2/2ch, 48khz 20bps<br><br>or do you have one like this (from memory):<br><br>...<br>INFO: Audio ch 0 format: ac3/2ch, drc
<br>INFO: Audio ch 1 format: mp2/2ch 48khz 20bps<br><br>The first one had only mp2 sound track and worked as expected, the second was the faulty AC3 encoded intro video and needed the audio track changing. Try my fix?<br>
<br>regards<br>dave s<br>
