Hi list,
only lately I paid attention to a message that maybe was there all the time, 
and I think some audio sync problem I'm experiencing could come from this. 
Every time I try to encode a dvd (no difference if I first dump the content 
with -dumpstream or if I do it directly from dvd) to AVI with lavc mpeg4, I 
get this:

VDec: vo config request - 720 x 576 (preferred csp: Planar YV12)
VDec: using Planar YV12 as output csp (no 0)
Movie-Aspect is 1.78:1 - prescaling to correct movie aspect.
videocodec: libavcodec (720x576 fourcc=58564944 [DIVX])
Pos:   1.1s     29f ( 0%)   0fps Trem:   0min   0mb  A-V:0.081 [72:1536]
Skipping frame!
Pos:   4.4s    112f ( 0%)  52fps Trem:   0min   0mb  A-V:0.081 [569:1536]
Skipping frame!
Pos:   9.1s    231f ( 0%)  39fps Trem:  74min 2273mb  A-V:0.023 [1087:1536]

The number of skipped frames may vary from dvd to dvd, but for one dvd it is 
always the same.
What's the best way to handle this situation?
