Windows 7: ComproDTV4 image quality

hello everyone,

I have a Compro VideoMate TV SAA 7134 tv tuner. On Windows 7 the image is fuzzy. On a nother drive i have the old XP, on that, its working good, the image is cristal clear. I suspected something with the deinterlace, but whatever i change in the settings (there is a slider for deinterlace in the panel), the picture quality remains bad. Anybody can come up with any ideea, how it can be fixed? It's Windows 7 32 bits, Ultimate.
Btw, never managed to make it work with the media center.



thnx and regards,

so? nobody experienced something like this?
