While trying to repartition my hard drive, I ended up with an unbootable system and had to re-install the OS - WindowsXP Media Center Edition.  Fortunately, I had paid for the reinstallation disk (a DVD, actually).  Anyway, I have Windows re-installed, and I installed all the drivers that the Dell Resource CD said that I needed.  However, when I try to setup Media Center, I get a message that says "Decoder Error.  Either the video decoder has malfunctioned or is not installed.  Please restart Media Center or restart your computer."  Searching the Microsoft knowledge base, it appears that I don't have an MPEG2 decoder installed, which I need to watch TV.  I can't figure out where to find that.  It apparently isn't part of Windows, and it doesn't seem to be on the Dell Resource CD.  The Dell hardware tech said he couldn't help me and I would have to call their pay service for software problems.  Before I spend big bucks, I was wondering if anybody can tell me where to get this decoder?  I have an ATI TV Wonder Elite tuner card.

 

Thanks,
