Vista - windows media center vista 64 tv tuners

I had a hauphauge 150mce single tv tuner set up and working in vista 64 it
worked fine for 4-5 months and then I got a corrupted signal, cable guy came
and confirmed the signal was good so I purchased a new hauphauge pvr 500
mce(dual tuners) and found that wmc still wouldnt work I get a corrupted
signal and wmc shuts itself down saying low signal strength, I loaded a fresh
install of vista 32 bit, same thing, but I then downloaded a free trial of
beyond tv 4.7 and that works, so I know its wmc. Does anyone have a fix, or
know if one is coming out in vista's 1st service pack is that coming out in
the new year, and is there a decoder software package that will work with
vista64bit, BTV4.7 only good for 32bit.

it used to work fine). When I uninstall WIN TV, MC works great again.
If you find a fix, please post it here as will I.

BTW I'm using CD version 3.4D1, the latest from the Hauppauge Website.
Does anyone have an older version? Maybe that's the key!
