finally here!!!
from hauppauge... post your results. im not trying until later tonight.
You can enable QAM by running the attached registry file. Save the file and rename the extension from .txt to .reg. Run the file by double clicking on it. Answer “Yes” to adding the information to the registry and then reboot the computer. A few caveats should be made clear to you before you enable QAM in Media Center. Clear QAM tuning is not on by default in Media Center because Microsoft is still having issues with their tuning schemes. Media Center appears to scan the correct QAM channels but seems to tune the wrong programs. They also have issues with major minor tuning. These are entirely Microsoft issues within Media Center and we do not have any workarounds for these problems, any fixes for these issues would have to come from Microsoft. Also, if you run this registry patch you will break digital tuning (both QAM and ATSC) in the WinTV application and ATSC tuning in Media Center.
... save to .reg file and run

; NOTE: this file should ONLY be used to enable Clear QAM support on Fiji
; (ie, "Windows Vista Media Center Feature Pack 2008")
;
; Using this file WILL break applications that only support the legacy "ATSC Network Provider"
; Apps must be recompiled to use the newer "MS Network Provider" if this file is used
;
; These keys control exposing support of Fiji compatible QAM for various ATSC products
; (of course, the HW products must be physically capable of supportting QAM!!!)
;
; You MUST restart you system after this file is installed for the changes to take effect
