Can you try renaming or removing ~/.mplayer/config or commenting the "tv="
lines out. I've made no use of chanlist, instead I set freq=0 and chanlist
and freq are mutually exclusive options.

Note: btcontrol can use channelset but kbtv only uses frequencies.

A \n sounds good, but it is not so handy if you want to call btcontrol from a
program or script. I might change it...
"get all" is a no.

I assume that this is not an issue for you. I don't see this (but I use
mplayer built with runtime cpu detection).

^^^^^^^ I dont know this one

Device busy happened/s often to me while messing with the code and testing.
Usually after it had croaked, but there was an mplayer left hanging around or
the driver was left in the cold (whatever that means ;) Waiting a few minutes
actually helped most of the time (maybe even reboot). You can always run a
manual mplayer -tv blahblah tv:// to see if bktr is back for business.
Another thing I found out is that you can't unload bktr.ko.

Yeah, if mplayer drops out, everything goes down.

Could have written that earlier ;-)
Can you verify that if config is removed you don't get this (from above):
TV channel names detected.
Selected channel: E8 - A1 (freq: 196.250)
(just to be sure that it's not somewhere else as well).

It may help if I explain a bit how it works: mplayer gets run like this (many
parts omitted): mplayer -tv freq=0 tv:// After that btcontrol is used to
change freqs (so that we don't need another mplayer) and other things.
btaudio module handles audio, not mplayer. Only for changing rendering
mplayer and with it the driver is restarted.
If you run mplayer or fxtv as you normally do and then btcontrol set frequency
196 does that display A1 as it should? If that is the case I might be able to
get away with removing the freq=0 part and just let whatever config is there
take place, because everything after the initial start is done by frequency
through btcontrol. And what does btcontrol get signal say at that freq? And
if you btcontrol set frequency 0 (provided that works)? Concerning scanning:
it may help to lower threshold. The "signal" is a bit of a constructed
parameter representing status rather than a real signal (not all bits may be
significant and so representing it as a percentage for a threshold is a bit
of a stretch).
The reason I use frequencies is because here in Holland almost everyone is on
cable and the providers have their own frequency tables, and they are locally
different. I've tried to use the channelset and it would produce channels
alright but with many duplicates, that is more than one channel numbers with
the same freq. So I am also not familiar with channelsets. This may be the
same reason why the kmplayer author uses frequencies (but kmplayer restarts
mplayer everytime you change frequency and bktr likes to freeze up if kicked
to often too fast). Also, a (working) frequency scan should always get you
your channels, though you have to name them yourself.
Does the "hardware info" show the correct things?
FWIW: with both my cards I didn't (have to) set any sysctls. The Miro I mostly
use sets them all to -1, a wintv card I have sets tuner and card number, much
like yours.
If needed I will create a test script that gives me any parameter that might
be suspect. And rinse and repeat. Eventually the %^*& thing is going to work.
Perhaps for my first PyKDE experiment (or C for that matter) I shouldn't have
picked something involving hardware :)
