Hi Randal,
>A few questions and things to try:
>
>1) Which version of the driver are you using
I tried the following with the 3.0 SNAPSHOT 0205
>
>2) By "the display changes too" do you mean that when you, for example,
> adjust the brightness up, you see the screen get brighter?
Yes
>
>3) When you change tuner/video, what visual cues do you have that anything
> happened -- you said you see the video signal change?
Yes. If I use xtvr I can HEAR the voice but only see snow on the window of fxtv
>
>4) As the screen gets brighter do you see solid white or do you see any
> background static in there?
At the end I only see a white screen...

I see the colorbars !

>6) If your card supports it, run in other color depths (8,15,16,24,32 bits

8, 15, 16 and 24 Bits no change :-(
