    TV tuner not detected error. Please help.

    Ok, here's my problem:

    Running Vista Home Premium 32-bit. Have a Hauppauge WinTV-PVR 150 MCE working with mediacenter. Everything's set up and working, apart from the poor onboard Intel GMA graphics, which fail to properly set the resolution (using VGA connection. TV displays "not support"), resulting in a black-screen on the HDTV.

    Recently installed a Gigabyte Radeon HD 3450 (this one) for the added features and hardware-assisted decoding (not to mention audio over HDMI is great. It's actually an HTPC setup for my dad; whos not too computer literate and the less cords the better rolleyes.gif )  The Radeon does exactly what its supposed to. Properly sets res over HDMI; crystal clear picture. audio over HDMI works flawless, reduced CPU usage, Perfect. (infact I highly reccomend the card for an HTPC setup)

    Suddenly Vista MC complains that it cannot detect tuner hardware. A quick check of device manager shows that all the hardware is set up, drivers installed, and (according to windows, anyway) functioning correctly. Googling the problem results in a possible fix (setting "Media Center Reciever Service" as local system service or something - cant remember exactly, did it step by step from the guide on HP website) which did not help. All other information seems to end with people throwing up there hands and saying something like "sometimes it happens, can't fix it".

    I know the tuner works, other apps can use it. The problem persists without the radeon present (using onboard Intel Graphics; standard monitor+VGA)

    Ideas? Please?

    I had thought of using mediaportal or some other free mediacenter but that presents the problem of no free EPG data. Is there any way to use Vista MCE's epg service in 3rd party apps, directly or indirectly? (I do doubt it. that seems like something Microsoft would be very dilligent in locking out)

    Maybe the video drivers of the new card stepped on something. I would remove the tuner from the device manager, reboot, and see if it's rediscovered.

    I tried that, unfortunately. No problems with windows discovering the device, however VMC still doesn't. I also tried re-arranging its positioning on the PCI slots. I know with some other devices (Creative SB X-FI for one) problems can occur if they are too near another device they don't like. Still no dice Tongue Tied [:S]
