[DVDnav-discuss] Crashes when opening a .iso or .img that is incomplete

[Janton Koster]

Dominik helpt me a bit to find the error problem:

libdvdread: Invalid IFO for title 16 (VTS_16_0.IFO).
libdvdnav: ifoOpenVTSI failed
mplayer: /home/rathann/build/BUILD/libdvdnav-4.2.0/src/vm/vm.c:1544:
process_command: Assertion `0' failed.

Dominik asked: This is probably because the ISO is incomplete. Would it be
possible
to upload a complete file?

This is exactly what the problem is, i was talking about incomplete iso or
image files.

Eric can you do something with this information? i can offer 10 euro with
paypal :-)
