[QUOTE="Paul S, post: 78782, member: 20531"] I guess that it's safe to rule out CPU overload. Your system looks beefy enough to handle everything. The only thing I see is the power supply, 430W is ok but is it enough? That being said, I have a 430W PSU in my main rig. It's running WMCE, and has P4 3.06 cpu, 2 300GB SATA drives and an ATI X850 XT Platinum 256 AGP. I had horribly jerky video on that rig, until I installed the ATI X850 and the SATA drives. I also replaced the original PSU that was 300W. The picture on that is excellent now. (I'm using the ATI drivers.) I also don't try recording analog while watching digital. I don't even want to try, now. I was just checking the CPU usage while watching TV with the Air2PC card. It ran around 80 - 90%. That could be the cause of some of my trouble. My test rig has only a ATI 9600 Pro AGP 128MB. That may not be enough. Just a thought. If you have seperate drives for recorded TV and for the live TV buffer, this could help. I think that is how I set up my main PVR rig. Keep pluggin' away at it, you just may figure it out yet. Paul [/QUOTE]
