1. I run winamp free edition on both x86 and currently on x64 Vista home premium, no issue. I believe on the x64 Vista there is an imcompatible driver or something but it went totally away after the first prompt. I can't even be bothered about it. Winamp is my primary Mp3 player, no problem for me. 2. Mine shuts down every single time.. It takes longer time than XP due to the many services it is running in the background. 3. I believe your media player is using a overlay draw method not compatible with Aero. I use the Media Player Classic, that comes bundled with K-lite Codec Pack, it has the same problem as what you experience with the player's default settings. Which is set to Overlay. I changed that VMR7 or VMR9, and the video output is able to run together with Aero. Try it. It is not a problem with the video file or Vista, it is the way the media player outputs the picture. And it is also a limitation on Vista side that the Aero interface cannot be run together with a older drawing method, which makes sense since better video quality can be achieved with newer renderer. 4. Setpoint 3.30, I used x86 and x64, no problems. My mouse is Logitech G7. All settings are functional. 5. OpenGL? nvidia and ati will do something about it. Just sit tight for a while.
