Assert failed when using libdvdread in vlc
Hi, there is a low priority bug report against libdvdread at: http://bugzilla.redhat.com/770720 I'm not able to reproduce it myself, but the original reporter is able to reproduce it every time using these steps: 1. Create a DVD on Toshiba XS32 2. Create image on hard disk with K3b 3. Play image with vlc Actual results: vlc gives "libdvdread: CHECK_VALUE failed in /builddir/build/BUILD/libdvdread-4.1.4/src/nav_read.c:264" Expected results: No messages Cheers, Honza

CHECK_VALUE isn't an assert, it just prints a message when something doesn't match what is expected. An assert would abort if NDEBUG was not set when building libdvdread. The message is being printed because dvdread is seeing a non-zero value in a reserved field that is suppose to always be zero. This sounds like a bug in k3b to me. -- John GnuPG fingerprint: D0EC B3DB C372 D1F1 0B01 83F0 49F1 D7B2 60D4 D0F7

Thanks very much for clarification. Honza
