Processor upgraded now Windows Media TV tuner does not work

I upgraded my processor form an AMD 5200 to an AMD 6400 and everything works
fine except for my TV tuner in Windows Media Center. I get a message that
says "Digital Cable device registration application stopped working and was
closed" The tuner card is a Hauppauge HVR 1600. I have tried uninstalling
the tuner card and reinstalling it both physicaly and in Device Manger. I
have tried removing and reinstalling my Nvidia 8500 GT video card too, but
with no success. If I launch Windows Media Center everything works until I
go to TV then I get a message that says "Windows Media Center has stopped
working" close program. When I close the program then I get the message,
"Digital Cable device registration application stopped working and was
closed" I have looked for a way to re-install Windows Media Center but can't
find one. I went on the web and found a thread that said to look for your
DRM folder and remove the contents then reboot, but my DRM Folder does not
have anything in it. I have tried reinstalling my motherboard BIOS, and my
sound and motherboard chipset. This is very frustrating!!! If anyone out
there has a fix or just something to try please let me know. I don't want to
reinstall my Vista Ultimate but am getting close to doing so. PLEASE HELP
!!!! THANKs

Go thru the procedure again, a processor change from what I've observed
always trashes DRM. I've been thru processor changes several times with MCE
2005 and it's always the same, the DRM must be repaired.

Enable hidden folder and file viewing in Vista.


1.. In Windows Explorer, choose Organize > Folder And Search Options.
2.. Click the View tab in the Folder Options dialog box.
3.. In Advanced Settings, select Show Hidden Files And Folders.
4.. Deselect Hide Extensions For Known File Types.
5.. Select "show hidden files" and "enable to see system files".
6.. Click OK.

7. Go to C:\ProgramData\Microsoft\Windows\DRM delete all files
setup your tuners again

In the past, AMD CPUs required special drivers to solve some TV & other
problems. Perhaps your new CPU requires new drivers (download them from
the motherboard maker or AMD - I've forgotten which).

Your referring to the Dual Core Optimizer which is availed here
http://www.amd.com/us-en/Processors/...1_9706,00.html

While the optimizer is required for all X2's I've encountered to play games
and some video types properly, in this case it sounds more like DRM
problems. It has been my experience with MCE 2005 that a CPU upgrade forced
me to reactivate Windows in less then 30 days and repair DRM.

I tried changing my settings in Windows Explorer to show hidden files and
there was still nothing in my DRM folder. So just for kicks I deleted the
folder and put a clean DRM folder in its place. Still have the same problem.
I talked to another guy who said to try uninstalling my devices under the
Safe Mode which I did, but that didn't work either. I looked in my Control
Panel under Report Problems and Solutions and I had 47 times this message
came up "Digital Cable device registration application stopped working" so I
sent it in through there report process and it now says it is being
researched. I am about to wipe the drive and start over, but I am afraid I
might have problems registering my Vista again, plus I would be looking at
about 10 to 12 hours downloading all the updates and installing all my
programs again. I thought about doing an install over the top, but I am
leary about other issues coming up and I want a clean load like I have now.
OH the joys of working on computers! I really appreciate your feedback and
am still willing to try anything else you or anyone else might have to offer.
THANK YOU!!

Before you nuke the OS go here and follow the detailed instruction from
Microsoft.

try renaming the folder and creating a new one

YOU ARE THE MAN!!!! or WOMAN!!!! which ever the case may be. I
unchecked the "Hide protected operating system files (recommended) box in
Explorer and was able to see another DRM folder. I renamed that folder to
DRMbackup, and POW it worked. I just can't tell you how much time and
headache you saved me!!!! THANK YOU, THANK YOU, THANK YOU!!!!!!!! YOU ARE
AWESOME !!!!!

Your welcome, glad to help and thanks for posting that the procedure worked
for you. It could help someone else in the future to keep in mind the
problems DRM can cause.

I've been it the same situation several times and knew clearing the DRM
folder worked for MCE 2005 but haven't had to try it on Vista yet.

I am having this problem after installing a new dual core processor. I have
tried the sugestions but to no avail. This problem also affects Zune. And
when I go and try to update the drm licence it crashes IE, I do not want to
reinstall vista ..... HELp

Another reason to hate DRM.

I just upgraded to a quad core and had the same issues listed here, the fixes also worked (a BIG thanks by the way)

I had IE crash on me too, but I got it worked out by starting up in safe mode with networking, taken care of both of the DRM folders while in safe mode and going to the the site mentioned for the reset
http://go.microsoft.com/FWLink?LinkID=34506
it was the only way I could get IE not to crash while trying to upgrade.

By the way I am using Vista Ultimate 32bit.

I am very happy that I found this site this time before I wiped out my HDD again, which is what I did last time when I upgraded my CPU.
