ATI HDTV wonder in MCE 2005

I have installed HDTV wonder on MCE 2005 (with latest rollups). Downloded and installed drivers from ATI. Device manager shows DTV.... installed but there are still four to five unknown devices. Because of that MCE application isnt working on TV.

ATI says HDTV wonder in MCE will require seperate analog tuner.

I know there are hacks like KRAM drivers; i tried on fresh install of MCE that too but cant get unknown devices off of device manager.

Any suggestions?
