Hi all.
I hope this is the right place for my problem.
Generally I have no trouble backing my DVDs up to a NAS using ffmpeg/avconv
through k9copy, but one set of DVDs gives me a headache due to a reported
duration of 1 sec and a negative bitrate. During the copy process everything
seems fine, but when copy is complete, the problem becomes obvious:
$ avconv -i unknown.mpg

$ ls -lh unknown.mpg

Interestingly, XINE gives a total duration of ~22 minutes when showing the
.mpg (actual runtime is ~41 minutes), but other players, in particular the
Plex Media Server and client which I use for everything else with that NAS,
are picky about this and refuse to handle the files in any usable way.
Is this a known problem? Any suggestions how to work aorund or fix this issue?
Thanks
Daniel
P.S. In case it matters, the problem occurs with DVDs of the TV serias ALIAS.
