Whats with all the rendering?

When I downconvert uncompressed 4:2:2 23.98 HD to NTSC 23.98 to make the file size manageable for offline I cannot playback the footage on the FCP timeline without rendering. When I playback uncompressed HD 23.98 with the presets set to 1080 23.98 no rendering is needed. I have tried setting the sequence, playback, and capture presets to uncompressed NTSC at 29.97, 23.98 with a variety of codecs. Any ideas on how to improve the workflow. All the rendering is a bummer just to play the clips in realtime. Using FCP 5, Tiger, 2.5 Gig dual G5, 8 gigs of ram, Decklink HD Pro dual link card, Fibre channel to S-Two disk array.

Sounds like a media type and sequence mismatch which forces you to render everything.

The Sequence Settings (under the Sequence menu) must match the properties of the media you're trying to edit. For example, if you're media is 23.98 DV, then your sequence must be set up the same way.
