CPU Usage
What should the CPU Usage be for the sagetv.exe process. The one I have installed is running at a 65% average. Every so often it will spike to 90% causing stuttering. Is it supposed to get this high? If not, what can I do to decrease it?

But you get that CPU usage when doing what? Recording, idle, playback?

For playback it's not completely out of line (a little high) but for recording/idle it's really high, those should be ~0.

The A7V is somewhat troubling, being based on a VIA chipset.

VMR9 causes issues on my box... Probably not VMR9 on yours, but you could try setting it to something else just to be sure.

Try disabling 3D Accelleration and using Overlay instead of "Default". Also check your decoder settings and make sure you have Hardware Accelleration (aka DXVA) enabled.

I don't recommend enabling hardware acceleration for that video card. It will reduce CPU usage a little, but you will likely get stuttering because of the video board's lowly graphics CPU. Focus on the video decoder setup.
I've got a AMD XP1700 (running at stock frequency) and usually doesn't get above 40%. But I don't use VMR9. I use the Sage Decoder, which is resource friendly.

Interesting, my 4 MX (way back when, before they released the 4000), did DXVA beautifully, allowing my AXP 1800 to play HD TS files.
