Post subject:	MythBurn driving me nuts..
I did one DVD of a single episode of a program. No problem. So i tried 3 episodes of something else. MythBurn ran transquant as it was marginally too big.. 1.04ish DVD burn't but no sound. Guessed it might have been the transquant as the other worked fine. So.. I did a lossless transcode (these are DVB-T recordings) to cut out the commercials and try again. Mythburn now stops due to an error whilst running mplex on the first file. Any ideas??.

I get no sound with burnt DVB-T recordings either.

The non-requantised ones seem fine on my machine. Is your DVD over (or even close) being full? R5B7 automatically requantises the recording if it's too big (check your log). However, this seems to lose the sound!

Hi Lem I have posted my fixes on a server ready for download see http://www.mysettopbox.tv/phpBB2/viewtopic.php?t=9311 also if you are having problems with requadrenting sizes being wrong try running lossless mpeg2 transcoding first this means that mythburn dosnt need to know how much has been edited/cut from the file before calculating the target size rgds simon

Thanks Simon, Yes I found that mythburn doesn't take cutlists into account when calculating disk size, so I did a lossless transcode to eliminate the commercials. However, mythburn won't create a dvd from these trancoded files! It fails at the mplex stage on the first file. It seems to run for a bit before falling over. Checking the temp directory I have a mpg file (with sound), a mp2 file with the audio, and another 'filename'(1).mp2 file that has no sound. It seems that either these transcoded files don't need mplex, or it's dropping out at the end of the process for some reason. I might try building the new MythArchive module - see if that can do it!

Can you post the log file it may shed some light on the matter Rgds simon if it is creating the mpg file with audio then mplex has completed ??

you could try remarking out Code: if [ "${cutflags[$idx]}" == "cut" ]; then echo "try to cut commercials using mythtv cutlist" # Obtain information about MPEG2 files from MythTV database ${scripts}/getmyth.sh $myfolder $mythtvlocation $file if [ -s ${tempdir}/cutlist.txt ]; then echo "cutlist found, applying and remultiplexing for DVD format" ${scripts}/mpeg2cut-px.sh ${myfolder} $videoformat $recode_ntsc ${mythtvlocation}/${file} ${tempdir}/${file} $factor checkreturnvalue else # remux to get DVD VOBUs inserted and fix potential audio sync issues echo "no cutlist found, remultiplexing for DVD format only" ${scripts}/remplex.sh $myfolder $videoformat $recode_ntsc ${mythtvlocation}/${file} ${tempdir}/${file} $factor echo "mplex worked" #checkreturnvalue fi else # remux to get DVD VOBUs inserted and fix potential audio sync issues echo "commerical cut disabled, remultiplexing for DVD format only" ${scripts}/remplex.sh $myfolder $videoformat $recode_ntsc ${mythtvlocation}/${file} ${tempdir}/${file} $factor checkreturnvalue fi the checkreturnvalue just after the remplex in mythtvburn .sh it should then continue onto the next stage its a bit brutal but at least you can see if this cures it then i can see if i can fix the returned value

That was my next line of attack Simon.. cheers for the pointer!

It's not deleting the m2v file etc, so I guess it stopping in remplex.sh, just after the mplex command. I've commented out the checkreturnvalue there.. Seems to be working...

Ok.. that works! Now, my DVD menu doesn't seem to work properly. I can manually change titles, but using the menu would be nice! Nearly there!

Post subject:	DVD Menu Not working in what
Lem, Have you tried the dvd in stand alone players or are you using xine I seem to remember i couldnt get xine to work using the keyboard, but now i have set up my ms remote i can get the menu to work. I assume you do have sound though, dont know why mplex is returning a error value but removing the checkreturnvalue. Rgds Simon

Success!.. Removing the -k switch in remplex.sh solved my menu probs. Thanks a bundle to simonf for all the previous help - much appreciated! I'll test my scripts with other files, then if any other UK DVB-T 'ers want to try them I'll post them up somewhere convenient.
