I have an Athlon XP 2800+ processor with an Epox 8VTAI motherboard. The BIOS and Windows XP both report the processor speed correctly as 2.08 GHz. However, when I try to either tune analog tv with a Compro usb 2.0 tv tuner or just try to capture composite video from an Avermedia A180 card my CPU is pegged at 100% usage and the recording is totally choppy?? I can't figure out what is wrong but I must have something set incorrectly because the Compro tv tuner claims you only need a 500 MHz processor to watch full-screen tv. I have a brand new 6600GT video card and I had the same results before with an ATI 9200SE card so I don't think this is the cause. Any ideas what is going on here? Thanks.
