[mythtv] MythDVD fails assert

[Chase Douglas]

I upgraded to Mythtv 0.20 last night and am very pleased. However, if  
I try to use Mythdvd, mythfrontend aborts. The output using  
mythfrontend -v all is:

2006-09-12 16:19:17.607 TV: Attempting to change from None to

libdvdnav: ifoRead_TITLE_VOBU_ADMAP vtsi failed
mythfrontend: vm.c:1479: process_command: Assertion `0' failed.
Aborted

I've tried to debug it, but when I fire up gdb and try to list  
ifoRead_TITLE_VOBU_ADMAP it says "No line number known for  
ifoRead_TITLE_VOBU_ADMAP" and I don't know how to fix that. The  
function is a part of libmythdvdnav. If someone could help me get gdb  
to work in debugging this, I would be happy to give it a shot.

Thanks,
Chase
