I've been reading this thread and I have also been having A-V sync  
problems (I use 1.0pre4-3.3.3) using 2-pass encoding. Basically, what  
happens is that the audio lags the video consistently by about 400 ms. I  
can easily oversome this when I'm playing my video with mplayer since I  
can just press the "-" key four times. However, a lot of my encodings have  
to be playable on windows (I use VLC for that) where adjusting the audio  
delay is much more cumbersome (though still possible). I've tried  
specifying the "-audio-delay X" option to no avail. It says that it's  
doing it but when I playback after encoding is finished the audio still  
lags by the same amount (the option seems to have no effect). I've tried  
downgrading to 3.90 but mencoder cries foul and says that version >= 3.92  
is required. My whole command for a particular movie is:

mencoder dvd://1 -aid 128 -vf scale=688:384,crop=688:290:0:50 -oac mp3lame  
-lameopts vbr=3:preset=128:vol=10 -ovc lavc -lavcopts  
vcodec=mpeg4:trell:cbp:mbd=2:v4mv:vpass=1:vbitrate=733

Same again for pass 2 with "vpass=2", of course. I've tried with cbr but  
same problem occurs. I've checked the lame site and the release notes  
don't seem to specify a new option in 3.92 that wasn't present in the  
previous one. I don't think this is a lame problem because I tried using  
mp3 encoding via lavc and I get exactly the same result. Another possibly  
related problem is that setting the volume in lameopts does nothing. Has  
anyone had any similar problems?

Adam.
