ATI TV TUNER - SATELLITE SET-TOP BOX - WMC - PROBLEMS

Is there anybody out there who could help me with an issue I am experiencing
with an ATI TV Wonder DIgital Cable Tuner? I am trying to setup the Tuner to
run live TV using Windows Media Center via a DirecTv Satellite Set-Top Box.
I know that the Tuner supports this functionality. I can sometimes get the
channels running, but often they cut out (especially if I go to movie
channels that I know I get) with a message indicating a Decoder error and
that the playback does not support, etc. etc. Often times when I try to
reconfigure the tv signal, WMC tells me that it can't find the tuner or can't
locate a signal. After a reboot or two I can reconfigure and get it running
again, but I still have the problem with the Decoder error. I have tried
calling AMD, Dell (who I purchased it through), etc. and they all seem out to
lunch. Any help would be greatly appreciated.

 

I'm not sure - but the Green Button website has forums with people who
almost certainly have the same hardware and probably the same issues

I'd ask there : http://thegreenbutton.com/default.aspx for media
center stuff.
