Or a -H (human) switch. It's really funny to switch to an other console

Yes, no problem. That stupid module used to panic my system when I
upgrade the kernel until I recompile it.

Permissions ? But since mplayer works ...

Yes, it works. I believe that __btcontrol can't set the frequency (but I
don't see anything in the console in this regard); however: while
scanning the sound remains from the same channel (the first one on
which I was when I quit mplayer so the channel is not changed, imo) and
btcontrol set frequency xxx as user gives "Open %s for writing:
Permission denied". You might want to drop freq=0 part anyway (I see no
reason if I exit the app while on my favorite channel to have to move
back again when I start it next time; I don't know why some all apps do
this maybe some card nee to be "initialized" ? )

 # btcontrol set frequency 0; btcontrol get signal
44

Nop.

Same here ( it's because of overlapping standards and compatibility for
different (older) TV sets. AFAIR). But as long as they're in standard that is
not a problem, imo.

True, if the increment step is small enough. You'll also catch a few FM
radio stations if you don't use cable but an external antenna.

This is a crappy card, no EEPROM so I force it via sysctl.

Hey, at least no one can tell you "but it works on windows" :-)
