Kworld ub435-q USB TV Tuner Now Works in Xubuntu and Kaffeine

With Xubuntu 11.10 "Ocelot", Kworld ub435-q USB TV tuner works great in Kaffeine Media Player v. 1.2.2 and KDE v. 4.7.4 for "over the air broadcasts" without any modifications.

A) Simply open up Kaffeine

B) choose "Digital TV" in the Start Menu

C) hit "Configure Television" option icon

D) Click on "Device 1" tab

E) Choose "Source" which for me was "us-ATSC-center-frequencies-8VSB" for over-air broadcasts

F) Close window, go back to Kaffeine TV window and click "Channels" option icon

G) In "Channels" window, make sure "Source" is set to "ATSC", then hit "Start Scan" button -- the scan took about 3 minutes and 17 channels were found -- I believe all that are in my area.

H) Once the scan is complete, highlight all channels found in the right-hand box "Scan Results" (or all that you would like to save) then click "Add Selected" and those channels will then appear in the left-hand box called "Channels"

I) Hit "OKAY" to get out of "Channels" window and you will return to Kaffeine "Digital TV" window with your selected channels appearing in the left margin column.

j) Double click on a channel to select -- and now hopefully you are watching !

Thanks Ubuntu and Kaffeine for programming for this tuner.
