Well, I just got a big ol suprise while doing some testing of framerates while previewing. See my other post - Preview Framerate Test.
While I was previewing out to OHCI/DV at preview quality, I wondered what whould happen if I made the VGA preview window really small. Bam, as soon as I dropped to 240x160 or smaller (vs: display at project size with any size window), I gained 4.5 Fps playback. Too cool. Sometimes it pays off big when you go and try to help other people.
Cheers,
