Window Media Center TV Tuner not found

I have Windows Vista Home Prem. and a ATI TV PCI Card. Media center was
working just fine til the other day when it can up with TV Tuner not
installed.
I have tried removing the card and rebooting, remove and installing the
drivers.
The card work well with ATI Media Center. the computer is a ZT P4 4gig
of DDR2
with SP1 installed.

Hi, I have the same problem. I've been searching all over the internet for a solution.

My problem initially stemmed from the ehrecvr.exe process causing a Media Center Error Message to pop up. I checked the details and it was being raised out of a .dll called raac.dll (which belongs to Real Player). Since I don't use Real Player, I tried renaming the dll to raac2.dll so the message would stop popping up.

It did, when I go into Media Center to click on live TV -- I get the "Tuner not Found" message. Check your TASK MANAGER --- I'm pretty sure that your ehrecvr.exe is running and using at least half your CPU. It is an executable that has to do with Media Center and exists in the c:/windows/ehome directory. Somehow, that process is out of whack...and I don't know why or how to fix it yet.
