Leadtek WinFast TV2000 XP problem

[oregano]

I have a Leadtek WinFast TV2000 XP card. When the TV application is running, the CPU usage goes up and down the whole time, between 11 and 26%. The hard disk is being accessed about every 3 seconds, which corresponds to the peaks in the CPU usage. Can anyone explain this?
The application (WinFast PVR) crashes frequently ("WinFast PVR Application has encountered a problem and needs to close").
Have checked the IRQ settings and installed the newest Leadtek drivers.
I have 'video in' on my graphics card, and had to disable nVidia WDM crossbar og video capture for the Leadtek card to work.
P4, 2.5GHz, 512MB RAM, WinXP.

Any hints appreciated.

What motherboard are you using?

For me, the winfastTV2000XP worked ok, but it does have some software issue.
the problem i bumbed in is that if I want to use a web cam, the TV card have to be disabled
so I'm not suprised that you have to disable your video-in on the graphic card for WinFast to work.
As the CPU usage goes up and down, i think is because the card uses software decoding TV signals
Once I was extracting a big zip file, and the picture of my TV2000 XP started to delay
