I have recently set up my new HTPC but have noticed that during DVD and Blu-ray playback the video stutters just a little bit every few seconds. It's not horrible stuttering but it's just enough that it's getting annoying, like it's dropping a few FPS. It happens with both ripped movies and disks. I know that the on-board video and audio aren't hugely powerful but surely they would be OK for video playback? Any idea why this is might be happening?

Also another unrelated question: Windows doesn't want to fill up the entire screen. There is a black edging around the outside about an inch wide that I can't get rid of.
Try updating your video drivers. Some driver revisions can occasionally have video playback issues, and can cause unstable framerates. To solve the black edging issues go into the AMD Vison control centre and go to the My Digital Flat Panels tab, check the box that says enable GPU scaling and select the option scale the image to full panel size. Also go to the scaling tab and make sure your Underscan/overscan slider is set at 0%, that should get Windows to fill the whole screen.
Installed CCCP Media Player Classic and did all of the things you said and still no luck. The stuttering continues.
I have noticed that it's not as bad when playing DVD's as it is when playing Blu-ray's. Maybe it's lack of graphics power?
