Hi, I've encountered the "pgc->cell_playback_offset != 0" error in libdvdread 4.2.0. I know a similar bug was fixed with the release of 4.2.0, but it seems that newer discs have changed something yet again. I downloaded and compiled libdvdread from svn yesterday, then compiled the latest version of ogmrip myself to ensure it was linked against the svn copy and can confirm the error still shows up when trying to rip the disc. The movie was Marvel's 'The Avengers'. It seems to play more-or-less ok in Totem movie player on Ubuntu, with the exception of selecting or skipping chapters. I even had to watch all the previews. Lots of "libdvdnav: chapter NOT FOUND!" and "Please send bug report - no VTS_TMAPT ??" in the console but other then that, fine. Attached is the log from 'ogmrip --debug', which consists almost entirely of output from libdvdread. Let me know if there's any further information that I can provide, I will be offline for possibly up to a week but I will respond when able to.

A gdb backtrace would be more useful. It is possible the problem is in the application rather than in libdvdread. We found a similar bug in HandBrake just yesterday. cell_playback_offset == 0 results in cell_playback == NULL results in NULL pointer access in application. -- John GnuPG fingerprint: D0EC B3DB C372 D1F1 0B01 83F0 49F1 D7B2 60D4 D0F7

Happen to have tried vlc? Sometimes I find it's able to handle these oddball dvd's a bit better, although I've not tested Avengers. Bryce
