[MPlayer-users] DVD-playing stops in 10 minutes

[Matias Griese]

The same problem is in every Linux DVD player I've tested last night.
Unfortunately ./configure reveals nothing; everything seems to be OK.

At least part of the keys are found, because I can watch all the movies
for 5-13 minutes before drive refuces to give more data. I just tried
vobcopy and I had same results:

 508MB of 7653MB
libdvdread: Can't seek to block 319912
libdvdread: Can't seek to block 319913
libdvdread: Can't seek to block 319914

So the problem seems to be in libdvdread (+ your version of it) or Linux
DVD driver. The unusable block is always (in 3 tested DVD's, both 4GB
and 8GB) exactly the same: 319912.

Regards,
  Matias
