    Here's the registry hack to enable QAM tuning for Hauppauge tuners. It does
    works for Hauppauge tuners and might help you get start in the right
    direction for your tuner. If your correct and your tuner is actually a
    Hauppauge then editing the registry to enable QAM support should work for
    Win 7.



    REGEDIT4
    ;
    ; 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
    ;
    ; HVR-1250, HVR-1290, HVR-1500q, HVR-1800, HVR-1850
    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HCW85BDA\Parameters]
    "AllowQAM_PowerToy"=dword:00000001

    ; HVR-1600 (only some models support QAM; should list them here)
    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HCW18BDA\Parameters]
    "AllowQAM_PowerToy"=dword:00000001

    ; HVR-USB2, HVR-1950
    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HCW73BDA\Parameters]
    "AllowQAM_PowerToy"=dword:00000001

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HCW72DTV\Parameters]
    "AllowQAM_PowerToy"=dword:00000001

    ; HVR-2250 (not yet supporrted)

    Win 7 MC supports clear QAM for any tuner card whose drivers support clear
    QAM.
    The hack you have linked to is to support clear QAM on TV pack 2008 not
    Win7.

    The HVR-1600 I installed with Win 7 would not register as a QAM tuner until
    the registry fix was applied. While Win 7 supports clear QAM it uses the
    same driver as Vista and that driver does not register the ATSC tuner as
    capable of QAM tuning. Been through multiple installs of both 1600 and 1800
    cards on both Win 7 and TV Pack and have all was had to use a hack to get
    them to show QAM tuning.

    Hvr-1600

    GREAT POST!!! If you create a registry file called hvr1600.reg and place the following text inside of it:
    ------------------BOF-------------------
    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hcw18bda\Parameters]
    "AllowQAM_PowerToy"=dword:00000001
    -----------------EOF------------------------

    (between the lines)

    You can automatically run a registry file that will install the required information into the windows registry for Media Center to detect the QAM feature of your dual tuner. The information in this file is for the HVR-1600 only. You still need the TV pack and play ready to get this stuff to work in vista. This file is only for vista - i'm not sure if it will work with 7.
