> mplayer -tv driver=bsdbt848:channel=28:device=/dev/bktr0 /dev/bktr0
It's not really a bt848 so various pieces of software unfortunately
don't work correctly with it. Only a subset of the ioctls are supported
and there's only one device node (/dev/tuner0 isn't supported ... all
access / ioctls go through /dev/bktr0 ... on my system I have tuner0
linked to bktr0). However, it should be a easy task to write a cxm
driver for mplayer.

Yep ... I see the same error here using your perl script.

I use the enclosed program.
