Sorry for the long discontinuity.  It's been a while since I have time 
to do some more tests.  So far I've tried "-mc 0" and the skip frame 
problem goes away but that causes a/v desync.
I've also tried "-vf pullup,softskip" and this still cause skip frames.

Finally, I tried using the "-vf filmdint" option, but the video still 
skips frames.  Here's my command line.

mencoder dvd://1 -fps 30000/1001 -ofps 24000/1001 -oac mp3lame -lameopts 
abr:br=128 -vf filmdint,crop=720:352:0:62,scale=576:240 -ovc lavc 
-lavcopts vcodec=mpeg4:vbitrate=768:v4mv:mbd=1:aspect=2.4:vpass=1 -aid 
128 -o output.avi

It looks like mencoder is trying to keep a/v sync by skipping frames, 
but forcing mencoder to not skip frames cause a/v desync...i don't know 
what else to try...am I the only one with this problem?

Thanks.
