I use DScaler, it is awesome and fixes any problems you will notice when watching high speed things, like sports games or anything like that.. also, DScaler is a TV viewing and Video Capture application that accesses the TV-Card directly and thus doesn't need drivers.
It is also FREE..
I have an old pci tv card from an old computer. one day i decided to throw it in (after cleaning off some melted rubberband and junk that had accumulated on it). I learned that they all use some standard chipset and was able to use DScaler to use it. I was surprised given its age, but now I have a resizable window that I watch tv in, and also it records very easily to incremental filenames.. I love it.. Can't believe I almost threw it away.. I only paid $30 for it about 6 years ago at a comp. convention..
emaili me if you want help or anything..
