My guess is that the video stream itself is corrupted, i.e., that they saved a corrupt file on the DVD because, as I stated, I tested with another physical DVD box that I bought.

On 4/22/14, Tuomo Sipola tuomo.sip...@iki.fi wrote: Hello, Summary: DVD playback freezes (or skips) on a physically OK disc. Is it a libdvd* problem? I have a DVD disc, Buffy 7th season R2 disc 6, which exhibits strange beahavior during the first episode, Touched. I have tested with two different discs from different boxes. I have also checked the disc with dvdisaster, so it is not a physical problem. The same problem occurs with VLC, mplayer and totem. Video playback freezes at 32:08 and depending on the player freezes for a long time (VLC) or jumps to 33:15 with blocky things briefly on the screen (mplayer). If I go to 32:09, the playback continues normally. Rewinding back to 32:08 freezes playback again. You may be able to get a stack trace while it is frozen by using gdb and ctrl+c when it is frozen. ___ DVDnav-discuss mailing list DVDnav-discuss@mplayerhq.hu https://lists.mplayerhq.hu/mailman/listinfo/dvdnav-discuss
