Ah, right. I was able to scan and find all of the local stations after
all. :)
Still no video output though. When I run xine and choose a channel it
stays in a "buffering" state and never displays video.  The same is true
with mplayer.

One more thing: when the device is configured in DTV mode, it generates
a bit more heat than it did when I tested it under Windows. I certainly
gets warmer than it does in analog mode. The antenna connector seems to
be sinking most of the heat, but there is  still more than I think there
should be. This, along with the problems mentioned above may be an
indication that something is not quite right with the driver.(?)

Markus: need anything else? I suspect you'll want logs with reg_debug
set to 2 while running xine?

Thanks.
