Not good to hear that you're having problems.
1stly, it's always advisable to get specific. What model is your tuner?
Searching the AverMedia site for DVB-T, TV Tuner and the keyword "hybrid" gives me this:
http://avertv.avermedia.com/Product/ProductList.aspx?Action=search&Kind=Product&interface=3&signal=2&keyword=hybridSo, what have you got?
In my case, I've got an
AVerTV TwinStar A825 and I've proven that it's functional, so I've got some confidence that your problems can be resolved.
What driver updates have you done for your tuner?
You could always take a look at Device Manager and see whether it flags any problem.
Another possible issue is that M$ MCE is locking the tuner somehow and not making it available for MC. That one's a bit beyond me - I'm running Win 8.1 so MCE is not supplied by default and I wouldn't opt for it anyway. I live in an MC household.
I'd expect that you'll have another contributor come along and offer some specific advice but until then, some basic checks and data gathering will at least be carrying you forward.
