Also, I still don't use Compressor for encoding my podcasts even though I now have FCS2. Check out ffmpegX, VisualHub, and MPEGStreamclip. IF you go back through the archives here, you'll notice that I have been favoring ffmpegX. I've just recently switched to MPEGStreamclip since it produces better results than the others. With ffmpegX I was getting videos with a darker gamma than the original, with VisualHub I was getting videos with a lighter gamma. MPEGStreamclip is juuuuust right.
Compressor has just historically been way to slow.
