iTunes Purchased Video not playing. Gray/no audio.

I've recently purchased from iTunes a few shows and whenever I try to play them not only do I have to authorize pc (even though already authorized) but it shows a gray screen with no audio and acts like it's playing on the slider?

Anyone know why this is happening? My other videos/shows play fine but starting to think it's due to me updating to 9.2. Have latest version of quicktime as well.

Any advice would be greatly appreciated!
