I pretty much use Photo JPEG @ 75% (at 60% if I go higher than Standard Def) or DV Pal.

Also, beware of interlacing, especially with DV. I have deinterlaced a bunch of stuff I have picked up in my travels. Clips will play fine in Quicktime player but in Catalyst they will stutter and you can see the jagged edge of the separate fields. I once forgot to set this in Juicer and it was a disaster. All the Jumbacks had that sawtooth effect. Had to go back and re render them all again!

Cheers
