Is this something that anyone has seen on AMD64 and FC3? I've got .18.1 
up and running (sort of) on FC3. Records and such just fine, but live TV 
playback gives me the color key error, then the following, and craps 
out. It might play about 1 or 2 seconds of video prior to dying. I've 
tried XvMC, libmpeg, OpenGL sync, video sync (experimental) to see if it 
was some combo of options. Another thing I'm noticing is that there are 
a lot of QT errors after the latest update I did. Finally, this is the 
latest 2.6.12 kernel from fedora. Is this the same issue or am I seeing 
something else?

Video hangs here and 10 or 15 seconds go buy and then I see this
