I have since downloaded the latest build from sourceforge, which Paul 
Raison compiled on 4/25. This still exhibits the same problem.

I tried the suggested built-in profiles, and even created one of my own 
which uses VDA, 2 CPUs, and no deinterlacing at all. I also checked my 
audio settings, for which the input had been set to something ALSA, so I 
reset it to CoreAudio. None of this made any difference.

For what it's worth, the GUI does seem slower than it did in the 0.24 I 
had been using. So your theory about Qt being a factor may be correct.

I'm going to try compiling my own version this weekend. If I still can't 
get it to work with VDA, I'll see if I can get Quartz to work (yes, I 
see the 32-bit only caution).
