Interesting one here. (I guess this is a bug report rather than a support request) I've just upgraded to 4K (build 213) and have Premiere Pro CS3 in XP and win7 32bit and win7 64bit on the same machine. Clips converted to CFHD from XDCAM EX flawlessly and play flawlessly everywhere - except...

in Win7 64bit they are inverted and pink in a Cineform project (whatever the playback settings). They play OK in, say, a Blackmagic project. They play fine in Windows Media Player.

I uninstalled Prospect 4K and reinstalled Prospect HD version 3, and the clips are fine.

I reproduced this same problem using PHD, CS3 and Windows 7 64bit.

Works OK in Win7 64 now. I installed the latest 4K update as administrator and in Vista compatibility mode and everything is fine. I don't know whether it's the compatibility mode or a difference between versions that's made the difference, because I've lost track of what I did before...
