decoder error with MCE 2005

[imported_Doughboy]

Hi all hoping for some help. I'm new to MCE.
I know everyone uses ge-force 6600 vid cards and nvdvd decoder. but I'm using my old spare parts (ATI Radeon X800XL). what decoder should I use if I'm using an ATI card instead of an nVidia card. I'm not able to view TV because I don't have a decoder installed

MCE rig specs:
P4C800-E dlx, 3.2GHz Northwood, 1GB Ram, X800XL AGP, HDTV wonder, TV wonder Elite, currently using onboard sound

You can use the NVDVD decoder with ATI cards as well. It's actually one of the better ones available.

But didn't the TV Wonder or HDTV Wonder come with one? ATI has a decoder package as well (though I think it's just the Cyberlink decoder).

I'll download the 30 day trial version of nvdvd decoder and give it a go. I think I read elsewhere that some people were haveing issues with certain versions of ATI catylist.

so, I may be getting more confused. what is the difference between nvDVD decoder & NVIDIA PureVideo Decoder?
