Full-screen movie Aspect Ratio on WMPlayer/PowerDVD/MicroDVD varies with the OS ??

[ukb007]

I have AthlonXP1700+, 250MB RAM, 80GB HDD, nVIDIA GeForce4, 3 partitions on my HD: C-WinMe, D-WinXP, E-usable by both; File system FAT.

When I display a movie on FULL-SCREEN in any player, it looks perfect in WinXP, but vertically stretched in WinMe. If I manipulate the monitor screen area with the buttons on my Samsung monitor to rectify the WinMe aspect ratio, then when I run WinXP the figures look fat (i.e., it has become vertically compressed). This happens in Full-screen display only. Of course, on non-fullscreen displays this is not a problem because the screen can be resized.

The solution may be absurdly simple for PROs, but I am really at a loss. Any suggestions?

Thanks.

Are you using the same screen resolution in both operating systems?

which players exactly do you mean?

have you tried MPC?

Thanks for giving it thoughts, gentlemen. I am using Color 32 Bit and screen resolution 1280 X 1024 in both. It's happening with WMPlayer and PowerDVD.
