Boxee support states that H.264 is supported but when I play files using that codec in Boxee I get a black screen with just the audio. I have the latest version of Boxee for Windows 7 64-Bit. My graphics drivers are up to date. I'm using an ATI Radeon HD 5770 graphics card. The videos play perfect in other media players with the help of the CCCP. Any idea on how to fix this?
