QuickTime vs. AVI playback speed

Okay, here's one for you. I found a clip on the web that I downloaded and tried to play back -- it's a PAL QuickTime .mov, shot at 25P. Playing back through my deck in PAL mode, it crawls along at maybe 20 frames per second.

If I export the clip as a .AVI, re-import the .AVI and play it back, it flies along cleanly at 25.000 fps.

Is this something endemic to Vegas -- that it just can't play back QuickTime files as fast as it can .AVI's? Or (more likely) am I doing something wrong? Converting it to .AVI means it takes a generation loss to re-render it, I'd rather be able to play it straight from the timeline...

To playback Quicktime, Vegas has to reach out to an external reader, decode it, put it back in the timeline, and upscale/downscale whatever it needs to do in order to play it back.
Kinda akin to frameserving, I guess, where Quicktime has to decode the frame information before you can see it.
