Here's the first
If you own a motherboard with a 690G/X1250 Chipset, when running on Win XP with the latest ATI drivers greater than 7.2, Media Portal will freeze when viewing the GUI. Keystrokes are still recognised and switching between fullscreen/windowed mode (ALT&ENTER) fixes it for a few seconds before the freeze occurs again.
There are 3 fixes to this.
1. Run ATI drivers version 7.2 or lower
2. If you run ATI Drivers 7.3 or higher drivers, you will need modified skins which can be located in the following forum thread
ATI 690G/x1250 problems
3. Upgrade to Windows Vista and use ATI Vista Drivers
NOTE:- This is a problem with the ATI XP Video drivers handling the .NET function of FLIPX & FILPY which produce a visual reflection on the screen. (Noteably for the music and video coverart)
