I've done a few more tests. I've upgraded to VLC 0.8.5, problems  
still persist. Interestingly, if I disable the use of shared memory  
in VLC's XVideo output plugin settings, DVD and 720p videos work as  
always, but the 1080i video sort of works. I get a very, very  
scrambled, less than full frame video image. At least VLC doesn't  
segfault.

I've also tested further with Xine and MPlayer and found virtually  
identical results in both of those. (However, my preferred player is  
VLC at the moment.)

For whatever it's worth, I'm using the x86-64 build of FC5 and x86-64  
builds of VLC, Xine, MPlayer, etc.

I have no problem running gdb, except for the fact I've never worked  
with gdb before. Can you point me in the right direction?
