Windows Media Center Decoder Error

I just reinstalled my OS after working for 4 years (it got so bogged down with extra stuff that reformatting was the easiest soltuion).  I installed all of the updates except for SP3.  Now when I try to watch something recorded in Media Center, I get this error:
'Decoder Error
The video decoder has either malfunctioned or is not installed.'
I've updated all of the drivers.  I saw this error one other time when I installed SP3 (that is why I'm avoiding it now), but don't know what could be causing it now.  Any suggestions?

you're missing the codecs for video, download divx and xvid

those are the two common codecs

I just installed both of those and restarted... still no luck.

Ok, I got it fixed.  I had to install PowerDVD, and there was a windows update that was affecting it.  Thanks for your help.
