Hi,

I recently got a lcd tv(philips 32pf9551), and it is working perfectly with 720p in combination with mediaportal 0.22.

However when i play a dvd with my xbox360 it sends a signal to my tv that this is a 720x576 resolution(576p).
This way the dvd is played in it's native resolutiion, however when i play a dvd with mediaportal it stays in the windows resolution of 1280x720.

How do i configure mediaportal that when playing a dvd it changes the windows resolution to match the dvd's?
Is it also possible to use this technique when playing xvid/divx videos(resize to 480p for all low res video's)?

PS: My tv does compensate for the resolution difference(removing black bars etc..) however it looks ugly
