On my primary desktop I have an ATI TV Wonder tv tuner card, and the software that came with it is ATI's own Catalyst Media Center. Overall it does it's job of displaying TV, but I am definitely not a fan of the user interface and the responsiveness of it (seems to have a big delay in performing actions like starting to display the TV signal).
Are there any good alternatives to CMC that are compatible with the ATI TV Wonder?
I should probably note that the system is running Windows XP 64bit edition.
