Yes!!!! And I thought I was the only one... I'm using WinXP SP2 plus all the updates with an ATI Radeon 9000 card. When using the mouse to, say, seek, or click a menu,
the whole desktop freezes (no mouse, no keyboard) and the only way out is the PC's reset button. The XP is a relatively clean install (two weeks old).
I've been having the problem on-and-off for six months. It appears to be linked to the graphics drivers and/or use of overlay video. I used to get it frequently with my old Hauppauge WinTV card (one of the reasons I bought a new card, the Compro) but I've also had it happen with Windows Media Player (playing video) and PowerDVD.
I thought at first it was a USB issue since I have a cordless USB mouse that I invariably used as a remote but I ruled that out. Thinking back, I then decided the problems started around the time I installed a USB WI-FI stick but last week I replaced the USB stick with an ASUS PCI-card and had a freeze with in half an hour Sad
Since the problem only occurs when overlay video is present and is not tied to any one application, I decided to roll back my video drivers. Part of the issue is that the recent ATI drivers clog the event log up with "Invalid Pixel Format" messages (
