Mencoder muxing problem with audio/video desynch


I use Kaffeine to record dvb to *.ts format ja remove commercials etc. with projectx. The I mux the *.mp2 and *.m2v files together with mencoder. When I watch the produced mpeg, I notice that audio and video are in desynch. Just why is this? Projectx shouldn't do this, so is mencoder a problem? With avidemux everything works fine.

The command that I use with mencoder:
mencoder -audiofile foo.mp2 foo.m2v -of mpeg -oac copy -ovc 
copy -o foo.mpeg
I really want to use mencoder with this!

Hmm not sure if this will help, but this is the commandline I use with mencoder to rip DVDs with no audio desync problems. Maybe if you use much the same, but change the input from DVD to a file (or files) it might help?

mencoder dvd:// -o outfile.avi -oac mp3lame -lameopts vol=8 -ovc lavc -ffourcc DX50 -lavcopts
vcodec=mpeg4:aspect=1.78/1:vbitrate=1800:vrc_eq=tex:naq:ilme:trell:cbp:preme=1:keyint=132:mbd=1:qns=1:vme=4:dia=2 -noskip
try for the "dvd://" part

mencoder "mf://*.jpg"
with the rest of the command the same

For example, change "mf://*.jpg" to the filename you have

I'm reasonbly sure the above won't work (there's no info / command about a sound file, which you seem to have separately) but if you mix and match with your commandline you already have it might help?
