Hmm, it seems to scan the channels.
I had to fix compile problems and made some format changes to make it more
readable.

BUT, it always scans the channels even when I don't use -tvscan (just
mplayer tv://1).

Btw, tvi_bsdbt848.c needs some cleanup because it wasn't using mp_msg
before your patch. A lot of perror remains in it, which has to be fixed
in another run.

- inactive
tvi_bt848: get signal 0x4
- active
tvi_bt848: get signal 0x2

I was looking at the chip docs but couldn't find it there either.
