Hi there,
I recently upgraded to Windows 7 Professional. Woot. But now whenever I run CS4 PPro, the video playback is choppy. When I had Vista Home Premium, CS4 PPro video playback was quite smooth. Why am I running into this problem now on Win 7? Any clues?
I'm on a quadcore computer, 4gb of ram, 512mb nVidia Video Card. And yes, all my drivers are updated.

I'm not sure I would have upgraded. Adobe has moved one application in its entire line of programs to 64-bit. Frankly, I don't think I'd upgrade any production computer's operating system (except as a test bed to see if it would work) until a version of that production software was released and verified by the company that makes it (as well as Microsoft) as ready for that new operating system.

@ Mark. Well Adobe said that CS4 is Win7-ready with no known issues yet. So the problem has to be on my end.
I decided to dual boot back to Vista 64-bit, reinstalled CS4 there. And the video preview played quite smoothly. No problems there.
So now I'm thinking that it is an issue of codecs. I uninstalled my K-Lite codecs and reinstalled them, but it still didn't fix anything.
I'm at a lost. I believe that it is an issue of codecs that affecting the video playback in PPro. If that's true, how can I thoroughly uninstall all the codecs? Or perhaps there should be certain codecs I need to get? If it isn't the codecs, can someone point me in the right direction? Thanks. I don't want to keep going back to Vista just to edit my videos. I like PPro to work on Windows 7.

Large codec packs can cause problems, usually are unnecessary as most editors come with the codecs that they support except for things like quicktime and 3rd party intermediate codecs and they are tested for use with their listed NLEs

My next upgrade path will be a Macintosh. So I won't be concerned with Microsoft's codecs but I will be concerned about gamma curves and how Apple likes to go their own way.
I think that Microsoft's Windows 7 introduces a whole new video player that is supposed to take advantage of new GPU hardware (this is a trend in general with computers). And I'll bet that is your issue.
Again, I would be reluctant to upgrade. You're getting a performance hit because you want to be the first kid on your block with the new OS and the old editor. If Adobe is saying that their editor will definitely work with Windows 7, then I'd try to open a support case with them and ask how to configure your system.
