MCE 2005 & ATI 8500DV ?

[Spinman]

I have an old ATI 8500DV that I would like to use in an MCE 2005 system.

I realize that this card in unsupported in this application, but....

I would add a Hauppage MCE 150 tuner card for encoding and TV tuner operations.

I would only use the 8500DV for video processing. Would need to use the dongle for svideo output connector.

Googled a bit - but didn't come up with anything promising.

Anyone have any luck developing such an hardware application?

Thanks -
