WMC playback choppy and CPU Usage drops to 0%
When I watch HD video in media center either live or recorded i get choppy playback. Once playback goes back to normal or live tv stops skipping I can rewind and watch the video without any problem. This was a Vista machine and i thought a update to windows 7 might help and it did not. I added WMC to the Norton list so Norton would not run background scans while WMC is being used also did not help. No other programs are running while I am using WMC. I opened device manager and watched CPU usage and noticed that when ever the jerky playback happened the CPU usage would drop to 0 then up to 3 then back to 0 up to 6 back to 0 and so on. Once the jerky playback stopped CPU usage would be between 1-15% mostly between 3-7% but never at 0% while playback was good. Any Ideas? I am not really a computer guy so not sure what else to look at any help would be appreciated.
Here is what I have
Gateway PC
Windows 7 Home premium 64 bit
Intel Core 2 Quad Processor Q8200 2.33 GHz
8 Gigs of ram
Geforce GT120 video card
