I've been searching for 3 days and can't find an answer to this one. Please feel free to flame and provide a link if I've missed it =)
I have 710RC2 installed and running with UI2, and whenever I playback a video file (.avi, or DVD-disc) I cannot access ANY on-screen display or control playback to pause, show library, rewind, etc.. I am just using a keyboard and mouse, and nothing works during playback. Left, right, middle click does nothing. Pressing nearly every key on the keyboard does nothing. I can hit Alt+Tab and switch between the 3 windows running, but changing focus to any of them does nothing except show the playing video. I can hit CTRL+ALT+Backspace to restart the X server, which is oh-so-useful! Once the video finishes, it goes back to my library and everything works normally after that.
Here's my hardware:
Mainboard: Intel DG33TLM (using onboard sound and network)
CPU: Intel Q6600
GPU: nVidia 7600GT
Thanks very much for any help!
