It sounds like Media Player is running at different resolutions when you open it in Aero and without Aero.
"with a lot of Pixels".

Check out this Microsoft page....

Windows Media Player 12 is running very slow. - Microsoft Community

Are these videos on your computer or are you running them from the net?


The videos are in my computer.

i can't resolve this problem :(

Try uninstalling and re-installing media player.

Go to turn off Windows Features in the Remove Programs list, and uncheck it and click OK.

Reboot and go back in and recheck it and click OK again.

See if that helps.

Do you have to use WMP? I'd suggest using VLC or KMplayer. Most issues with WMP are not on those.
