If you haven't found it yet, someone put together a really good summary of installing, use, workarounds, etc for this card. I can't post a link yet, just search the forum for "ati hdtv wonder faq". It helped me immensely. There were a couple of counter-intuitive aspects to the installation. The two that stick out were that you need .net installed and you need to install the card after some of the drivers. There's also a more active thread going on now, but it's more about current users commiserating about how flaky the MMC app is. You can usually find that one on the first couple of pages of the forum. Hope this helps. Good luck.
