Yes, DVB.  When tuned to a known good channel/frequency, azap produces:

This is with the same piece of coax that normally feeds the QAM tuner
in my TV.  My TV is able to display this channel without any problem.

If I hookup my UHF antenna, I get this from azap:

# azap -c channels-8VSB.conf KNME-HD

And the picture is perfect.

Yup.  Tried that.  Mplayer and Xine both play the resulting file with
pixelation so bad, it is unwatchable.
