I am having a problem with Media Player 9 and am unable to find any reference to it in the knowledge base. On my system, I am running an ATI Radeon 9800 with 128Mb ram and a Philips 170W4 Wide Screen LCD Monitor connected via DVI. The OS is XP Pro. When I run Media Player 9 and insert a DVD, the player does not use the whole display (1280 x 768) but constrains itself to 1024 x 768. To clarify this, the video window is full screen but the content is only sized to 1024 wide which means that I have a letter box on the left and right sides as well as the top and bottom. I also use PowerDVD XP and this program correctly displays the DVD using the full screen. In both applications, the aspect ratio of the DVD is maintained. Do you have any suggestions that I can try, in order to resolve this issue with Media Player 9? I am looking forward to your responses.
