Pro tools le 8 + Quicktime Movie = Problems

[WyvernsSounds]

Hi Everyone,
i got a heavy problem. I have much experience with Pro Tools LE & HD, but i never got this Problem:
I importet a Quicktime Movie from my Hard Disk into a new Session. When I want to play it, Pro Tools play everything, but the Video just view one Picture of the Video. If I stop it then and start again, I get another Picture. I don't know anything about this Problem and I need to synchronize Videos for a Film. Please Help

What format are the quicktime movies you're using encoded in? Uncompressed DV or H.264 are your best bets for formats, there are a few codecs that require too much CPU to decompress on the fly while also running Pro Tools at the same time, so the video will glitch or not show at all.
