I've got a new Radeon HD 6870 with a x4 Phenom II 3.5GHz Windows 7 x64, and I'm seeing graphics glitches when I try to watch the videos. It looks like the at certain points during the cinematics that it isn't properly clearing the screen? I have attached a screen shot of what I see. I have tried the various options under the Setup but haven't had any luck. Tried x16/x32, 32 bit and low res textures, mip maps disabled, etc. You can see in the attached picture that the helicopter is still being shown in front of the pilot from the next scene, and as the scene rotates leaves streaks at the edges. Also, during the intro cinematic, when it is supposed to fade to white and then show the digital globe spinning, it just fades to white and stays white the rest of the movie. Any ideas?

[EDIT]
I've got it working now. I had to go into Catalyst Control Center and set the Anti Aliasing setting to "Use Application Setting". That fixed the problem with the smeared videos.

PS

I was having a problem earlier where models were not showing up, ie I could see the blades for the Pegasus, but not the chopper itself or the Antaeus itself, or any of the debris to recycle. I disabled the mip-mapping, and that seems to work properly now.
