[MPlayer-users] frames skipped when grabbing DVD

[Matus UHLAR - fantomas]

Hello,

I am trying to grab DVD to a local file and have issues.

mencoder -ovc copy -oac copy -frames 1000 -o dvd-1000.avi dvd://1

- I get many "Skipping frame!" errors:

When I add the "-noskip" option, first few frames are OK but later I get
this error:

Writing header...
ODML: Aspect information not (yet?) available or unspecified, not writing vprp header.

Too many video packets in the buffer: (4096 in 8249187 bytes).
Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.

In both cases I can't watch the movie, the first is distorted, the second
plays too slow. 

Has anyone an idea where could be the problem or how should I continue?
Recoding to mpeg-4 format works but I'd like to try something more without
repeatedly reading the disc...

Thank you.
