[MPlayer-users] stops always at 77th minute PARTIALLY SOLVED BUT ...

This morning I checked the DVD. As my mpeg4 encoded movies stops at the 77th
minute on my standalone reader, I do:

# mplayer -dvd-device /dev/sr0 dvd://1 -ss 4620 (4620sec = 77 minutes)

and I have nothing although the movies lasts 105 minutes.

In fact if I want to start at about the 77th I have to type:

# mplayer -dvd-device /dev/sr0 dvd://1 -ss 2780 (2780s not equal to 77 min!)

There is apparently a problem of timing while reading the DVD but the encoded
mpeg4 movies reads OK with MPlayer (not on the standalone reader!).

Unfortunately I only have one chapter thus I can't start at a chapter and I
have to lose a lot of time to see to which value corresponds 77 minutes when
reading the DVD with MPlayer.

Tcprobe -T1 -i /dev/sr0 says "too many video packets in the buffer" but does it
have a meaning.

It can be badly encoded DVD movie or problem with MPlayer/MEncoder? If anybody
knows a way to reestablish the rigt timing?
