Which version of Premiere Elements are you using?
Have you tried installing Quicktime 7? (You can select to disable to QuicktimePlayer.exe, as it is considered a security risk, but the other components can be important in working with MOV and MP4 files.)
Have you manually gone to the nVidia site and ensured you have the latest drivers for your video card?
hi i installed quicktime and it seems to work for now. it doesnt make any sense as i have been using exactly the same files just fine without quicktime. the files open in every other program except elements. im not sure why a fancy adobe program would need an ancient apple program like quicktime to make something work?
As I said, Quicktime does provide some components that Windows doesn't otherwise have.
