Synopsis::

I have my WinTv card connected to a Bell ExpressVu satellite receiver, and use my PC monitor for viewing. As I use the satellite for changing channels, the WinTv need only be tuned to one channel (4).

From within the setup app, selecting my capture card then autotune for television channels to get the frequency for satellite-WinTv connection; I get full signal strength. But when I go to view television afterwards all I receive is white noise for video and audio.

I also have Beyond TV installed, of which I get a working television signal (viewable on PC). Prior to XP I used Windows XP MCE and the MCE portion also gave proper channel viewing, though MCE seemed to crash frequently, which is one of my reasons for changing.

Any thoughts, suggestions, etc?
