Since I started using 17.0.122 the theater view video playback is a blank screen. If I change to standard mode (ctrl+1)and then back it works. The video is playing & sound is coming out. This happens on a fresh start of MC17 after that video plays fine. I use HQ settings of Red October & all my ATI drivers are current. This happens on Win7x64 with as well as Win8cp x64.
