Yes, Vorbis-only seems to be fine, and AVI only is still very slow.

Well, it's a 600MB file, so I'll see if I can grab a smaller section that has 
the same effect.  It might be difficult though, because it appears to be 
cached - on the first run it takes a while to read a few hundred frames, but 
Ctrl+C and run it again and those same frames are read pretty quickly.  My 
hard drive is also hardly going at all throughout the whole process.
