Itunes video not playing on 27" cinema display

[Doc750]

It will play the video with quicktime player, or VLC prayer with no problem. But if I try and watch the video through itunes I only get sound, and no picture.

If I disconnect the cinema display, I can see the video/Sound just fine on the MBP.

- I have tried this with multiple different videos on my itunes account.
- I have rest the computer
- Rechecked my connections
- Checked for all updates

suggestions?

thanks!
