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?
