Ongoing Video Not Completely Filling Widescreen (1 Viewer)

I have recently completed building an HTPC running XP SP2 using an ATI 9800 Pro with the latest Omega Drivers installed. The system is hooked up to my HDTV which maxes out at 720p through the ATI DVI-Composite adapter. Everything is working fine except when I change the resolution to 1280x720, the output is too big and some of the screen doesn't get shown. For now I have it at a slightly lower resolution, but this doesn't fill up the whole screen. Is there a way to adjust the display (ie. stretching, shrinking, shifting) to make the video correctly fill the screen?

Here are my overall system specs:
Celeron D 3.33 GHz
512 MB RAM
ATI 9800 Pro with DVI-Composite Adapter
Hauppauge PVR-150
WD 160 GB HD
Samsung DVD-RW Drive

    try hitting "S" while playback of video.

    Also goto MP->Settings->Adjust Screen
    There is a square, to adjust the AR.

    Thanks for the quick response. I guess what I really wanted to do was create a custom resolution to fit the screen exactly, but this would have been too much work. I ended up taking your suggestion and changing the screen calibration settings within MP. Thanks again.
