This patch doesn't work.
There are several problems.

After I apply the patch, the avi created with:

mencoder -ovc copy -o test.avi dvd://1 -aid 128 -oac copy

doesn't play correctly. Audio and video go slowly out of sync.
I need to add the option '-mc .1' to keep the sync.
Of course I cannot seek.
After fixing the avi with:

mencoder -oac copy -ovc copy -noidx -o new.avi test.avi

I can seek. The seek is better now, but the seek of the video
doesn't correspond to the seek of the audio. After the seek
audio and video get completly out od sync. 

I would guess that the patch is not complete.
