Hi All,
	I'm mailing the list with my work-in-progress because I
notoriously loose my work.  This is based on work by Björn Danielsson,
found at  It's a userland only driver.

	Anyway, I can reliably tune chan 77(?) 505.25 mhz, but it's
scrambled, I get the sound.  I can also control bitrate and
resolution.  It's just the darned tuner.  You need to turn the bitrate
down if you don't have usb2 (I don't) because usb1 just can't handle
the stream.
	TV, anything with frequencies really, isn't my forte so I'm
just fumbling in the dark.  Insight on how to choose frequencies would
be helpful, I think I might be having ntsc vs pal problems.
	I won't get back to it for another week or so feel free
to pick up where I left off.
