[MPlayer-users] skipping every even frame

[Bleck]

Encoding in one pass is OK. But mencoder skips every even frame when I try first (or three) pass encoding. I have already encoded some DVDs, using three pass encoding, and did have any problem.

This command runs fine :

mencoder -dvd 1 -alang fr -o video.avi -ovc lavc -lavcopts vcodec=mpeg4:vhq:vbitrate=1800 -oac copy


This command skips frames :

mencoder -dvd $ -alang fr -ovc frameno -oac mp3lame -o frameno.avi.

Here's the "full" output :
