Have you addressed the basic install steps?
http://wiki.jriver.com/index.php/Television#Install_the_TunerPlease make sure you look at the whole wiki entry on TV and report at what step in the process you have a problem.
If you've done all that then:
Drives & Devices > Television > TV Options ... > Advanced > Show Status...
should reveal the situation. There's an auto copy to clipboard. Come back here and post up the result.
After that, then it's an in depth technical problem. I repeat the comment, generate a log and follow the submission process (also, raise a separate thread under the TV board, your cries for help will tend to get drowned out in the high traffic areas).

I've seen a number of comments from the MC development team expressing reluctance to this kind of proposal. You're dealing with established precedent and policy. One for the custodians of the business.
