Setting up a 2250

[pcostanza]

Thanks William. I saw your post a few hours ago and have tried it with no luck. I'm still trying a few things to see if it will help.

I'm curious, does it work if you disable the QAM PowerToy reg setting? (Set it to "0".)

Code:

Windows Registry Editor Version 5.00

; 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

; HVR-950q
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HCW72DTV\Parameters]
"AllowQAM_PowerToy"=dword:00000001

; HVR-2250
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hcwPrx89\Parameters]
"AllowQAM_PowerToy"=dword:00000001

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hcw89\Parameters]
"AllowQAM_PowerToy"=dword:00000001

So far, I've not noticed anything different after this reg entry. Am I to do anything else after doing this, rebooting and running QAM manager?

[whurlston]

You'll need to reboot and then try running a scan with the center frequencies setting.

[pcostanza]

Done that. In fact, I just finished scanning trying each of the choices. No go. Things are still working great with QAM in Vista Media Center with either the 2250 or the HDHomerun.

[whurlston]

Just to make sure... did you change the values to dword:00000000 ?

[pcostanza]

Just for the 2250 listing. Am I suppose to do the same for the one listed below the 2250 entry?

[whurlston]

Sorry, yes. Both of those are for the 2250

[pcostanza]

OK, made the change to the last entry and still nothing. It might be my imagination but it seems like the scan from 1 to 159 is going just a tad bit faster than the other scans. I also tried a few of the other choices just to be sure and I haven't had 1 QAM channel show up yet.

[whurlston]

Can you post the logs from the scan with the QAM powertoy disabled?
