HELP! - Component Registration Failure

[Slugsie]

A couple of days ago, Vista Media Center started giving me the following
error:

COMPONENT REGISTRATION FAILURE
Some of the files needed to play radio or video are missing or corrupt.
Windows Media Center component registration may have failed.

Followed by:
Application Failure
A critical Windows Media Center process has failed. Please restart the
computer and try
again. If the problem persists, contact your hardware manufacturer for
assistance.

The error appears when I try and list the Recorded TV. If I try and watch
live TV I get:

Tuner Not Available
The Tuner is currently in use by another application or is not working.
Please close all other
applications, restart Windows Media Center, and then try again.

I have not installed any software or codecs since it was last working, and I
have tried multiple reboots. I can watch my already recorded TV files fine
using Media Player, so they're not corrupt or anything. I can also watch
other video files (DivX/Xvid encoded AVI files mainly) just fine.

Googling this error returns many pages discussing the problem for XP Media
Center, and giving a couple of solutions which I have tried with no success.
The solutions suggested include re-registering some of the ehome exe files,
and deleting possibly corrupt recordings.xml (I actually deleted the whole
TempRec folder to be sure).

Can anyone help me out on this???

My system is a home built one as follows:
MSI P6N SLI Platinum motherboard
Intel E4300 Core2Duo
nVidia 8600GT
4GB Ram
Hauppauge Nova-T 500 tuner
Vista Ultimate x64 with SP1 RTM

The current install is just over a week old as I did a fresh install for
SP1. All drivers are up to date as far as I can tell.

I have done an SFC /scannow too. No problems reported.

Slugsie,

I have had a similar problem. It was caused by the DRM (Digital Rights
Managment) Software within Vista. My system is also home built, unfortunetly
those of us who like to home build tend to change components regularly. My
problems were caused by changing components.

Have you changed any comonents within your system since the original build.
In particular CPU/Motherboard etc.... even if they are like for like changes
this will effect the DRM and cause the errors you are observing.

The solution in my case was to either return the original hardware or
re-build the machine.

Sorry.
