Vista Media Center and the ATI 650 TV Tuner

I have a desktop with Vista Home Premium installed and an ATI 650 TV Tuner
card. My ATI card lets me connect to both my HDTV antenna and my analog
cable. The problem is when I was running XP Media Center 2005 - the XP would
recognize the ATI has both connects and would automatically configure itself
for both TV signals.

ATI support led me to Knowledgebase article ID : 929011 - with that I got
and install the Hotfix from MS Support - however now - I can set up my TV
signal for my Analog cable -- OR -- if I want to watch HDTV - Vista Media
Center is forcing me to go back and reconfigure my TV Signal input for my
HDTV antenna.

Does anyone know of a way to get Vista Media Center to automatically
configure itself for both TV Input signals?
