There are a couple of controls (like "interlace") which are not really 
correct.  I need to straighten that out.

New potential goodies include better control of video filtering (which I'm 
hoping will significantly help with snowy channels) along with support of 
different video formats.

No promises yet, but from what I've read it may be possible to get this 
device to emit uncompressed video data, which _in theory_ could allow this 
driver to work with devices that don't deal with mpeg2 data very well. 
But that will take a lot of work and there are many pitfalls along the way 
(like perhaps having to get isochronous streaming to work or that the 
encoder chip's logic for this might have a bug) which might prevent it 
from working...  The upside however is tremendous.

I have an understanding for how to make VBI work now (thanks to Hans 
Verkuil and his efforts in ivtv).  I think I see a way to get the radio 
side working as well.

BTW, as far as I know, VBI and uncompressed video are not supported at all 
by the Windows driver.  :-)

Other driver work still to be done includes (1) segregating out the 
debugging stuff so that it can be selectively compiled / activated, and 
(2) more work to separate out parts which don't belong in v4l.
