Hi,

I have a Kworld ATSC110 and can not figure out how to choose between the
two inputs described on the box as "Digital Antenna" and "UHF/VHF
Antenna". Honestly, I'm not quite sure what they mean by that. I'm
assuming I could use one to watch Digital/HDTV broadcasts and the other
to watch traditional analog broadcasts (but not simultaneously).

The "top" input (farthest away from the motherboard-end of the card)
seems to do everything. If I plug my cable TV line into it I can get
analog and QAM256 channels. If I plug my "rabbit ears" antenna into it,
I can get analog and a few HDTV over-the-air channels. I've used MythTV,
tvime and mplayer with success on this input. The other input doesn't do
anything.

I've seen various reports of people saying which input works for what,
but I don't know how to actually select between them. I have NOT tried
this card in Windows (I do not have Windows) so I'm not sure which input
does what in that environment.

I'm using Gentoo with the 2.6.20 Kernel and v4l/dvb from mercurial
linuxtv sources from a few days ago.

Here is what I believe to be the relevant part of dmesg:
