once a upon a time I choose kaffeine over xine, mplayer and such,
because channel switching seems a lot of pain to be with the others
to me. 
And to setup the chennel frequencies and settings....uuuuhhh.

Kafeine: "Scan channels", "Add channels"...and you are done.

But may be my experience is to old in this special case.

By the way: 
xv is a lot of [CENSORED] with my NVIDIA card. I had a lot of trouble
to find a way to regulate brightness and such on a per application
basis. The only way I found (which by no means is to be read as
"there is no other way than..." ;) was to switch the xine
video interface of kaffeine from xv to xshm.

May be there is another chance in this corner of the problem to improve 
all this?

Suggestions are welcome :)
Very welcome.... :O)
