Here is an excerpt from the latest ATI Catalyst driver released today, note point 3.
The following section provides a brief description of known issues associated with the latest version of ATI Catalystâ„¢ Linux software suite. These issues include: * There is no support for video playback on the second head in dual head mode. Further details can be found in topic number 737-26985 * Desktop corruption may be noticed when dragging the overlay/video when using dual-display mode. Further details can be found in topic number 737-29578 * A black screen may be observed on some hardware when switching to the console or leaving the X window system when a Vesa framebuffer console driver is used. Further details can be found in topic number 737-30687 * Video Playback may display wrong colors and additional shadow images when cropping or expanding a video file using a video player that utilizes the XVideo extension Apparently ATI considers this a bug worthy of their attention, although from what I know the issue is not an exclusively ATI issue.
