Default Decoder Error - The video decoder has either malfunctioned or is not installed

I apologize if something like this has been posted earlier but the search option doesn't seem to be working for me right now.

I just installed a fresh copy of Windows Media Center 2005. I have a Radeon 9700 installed along with an Xtasy Theater 550 card. When I try to set up my TV connection it tells me "Decoder Error - The video decoder has either malfunctioned or is not installed."

I check Visionteks website (they make the Xtasy card) and their site says a fresh install of Windows Media Center does not contain a required MPEG-2 Decoder and one is required to work.

I installed the Microsoft Windows Media Decoder CheckUp Utility and it says no MPEG-2 Decoders were found on my system. Can someone let me know just what I need to download or what I am doing wrong? I find it odd ATI didn't include anything in their drivers.

EDIT.... I am using the catalyst 5.12 drivers and the latest Multimedia Center installation from ATI. During installation of the MMC it says a DVD decoder was not found so one wouldn't be installed. Not sure if that helps at all.

You need to either one venture out to a computer or electronics store and find a recent edition of PowerDVD or WinDVD. Or alternatively you can goto Nvidia's website and download the purevideo decoder for about 20 bucks(USD) install and you'll be all set link is below. you can uninstall the ATI Multi Media Center it's not required, but if it will work you can install ATI's dvd decoder(download the file from ATI's site or find it on the cd)and see if it sorts out the dvd decoder problem in MCE I doubt it will though.
