Canon 5D MII .mov files video is jerky

Question

Vista 64 Ultimate SP1
Using latest ASUS i7 MB P6T Deluxe w/ Intel 3.2ghz 965 quadcore @3.2 ghz
12GB Ram
Nvidia Quadro CX video w/latest drivers. dual Dell moitors 2408WFP running 1920 X 1200 via DisplayPort.
Premiere Pro CS4 latest updates
Quicktime Pro latest updates (7.6 1292)
I can open the .mov files and they play smooth as silk in QT Pro at full rez.
When I import the .mov files into PP on the timeline and go to play, I get stalling, horrible framerates (on the order 3 fps), intermittent muting in the audio. Horrible. Help ! I sunk a lot of money into this state of the art rig to edit uncompressed HD video from my Canon 5d Mark II, and yet
I am at my wit's end. The .mov files from my Canon 5D mark II are allegedly 1080p, 30fps h.264 (?). How do I get PP to play and scrub through smoothly uncompressed on the timeline ?
Thanks

John,
Byron, the British Poet, has a great pair of lines in one of his works that is very appropriate here:
'These thorns are of the tree I planted.
They tear me and I bleed...'
For a New Yorker, I detect a certain glaring lack of the built-in up- front protective cynicism about product promotion that I would have expected to find. :) WTF is an appropriate afterthought though. And it does establish that you at least got some of the proper upbringing to be a bona fide New Yorker :)
By the way, do not hold your breath until an Adobe rep steps forward to offer a rebuttal for misleading advertising. That's even less likely than a real New Yorker apologizing for saying FU. And, don't be surprised if that is not the only instance of gilding the lily you will discover in Adobe--or many other--software product claims.
However, you can get your money back from Adobe, though, if you haven't had it too long. They are quite good about that. And, they were up front about the QTP requirement. And they do have some great products, like AE, that actually live up to the advertising.
And, most importantly, out of all this you have certainly learned one half of the lesson necessary for a successful relationship with new software--Read the forum, search the web for 'X Software Problems' and hit the other related forums like DVI, etc.
Now for the other half, the cherry on top, the most important step before buying: Are you Ready!
DOWNLOAD A TRIAL VERSION AND TEST THE #$%@ OUT OF IT WITH YOUR CAMERA GEAR ON YOUR COMPUTER CONFIGURATION BEFORE YOU BUY. And it never hurts to try the competition's software before you jump.
Never, absolutely never, take any marketing claim from any software producer to be necessarily true to YOUR computing requirements.
As a potentially full fledged New Yorker (with a bit of re education, that is)I'm sure you will appreciate my F&%$#$G candor :)
