I have a feeling the desync has to do with the cut marks I have created and processed with vdr on the recording. It appears we lose ~200ms of audio for every cut mark that is created and processed by vdr. I have experimented with other demuxers and lvedemux appears to work as well. What I have done is count the blocks of video and multiply that by 200ms. Then use that calculation in the "time shift" switch here (-sh): mkfifo file.m2v file.mpa cat 00*.vdr|pes2ts2 100 101|ts2ps 100 101 > file.ps lvedemux file.ps | lvemux -p -1 -r -sh -400 -v file.m2v -a file.mpa -o file.mpg Note: -400ms would be for a recording with two blocks of video (-600ms for 3 blocks, etc..). This is to compensate for the loss of audio on the cuts. > >> >> >>> I patched the bitrate because the nominal 15000 in digital.ts (that >>> seems to be fake) is not correct for dvd. >>> Besides a resolution of 528x480 is not valid either, but most modern >>> players will accept it, so re-encoding >>> is not worth the hassle. >>> >>> For hdtv the basic command is: >>> >>> $ mencoder -of mpeg -mpegopts format=dvd:vbitrate=9000 -o hdtv.dvd -oac >>> copy -ovc lavc \ >>> -lavcopts >>> vcodec=mpeg2video:vbitrate=5000:keyint=18:mbd=2:aspect=16/9:vpass=1 -vf >>> scale=720:-10,expand=720:480 >>> >>> >> >> >> When I attempt this next command line with "mpeg2video", i get an >> error saying >> missing "mpeg2video" codec.

I also have just about everything enabled that I can. I am assuming that the mpeg2video codec comes from ffmpeg? Thanks for the help.. Regards, C.Y.M.
