I don't think you need to write a driver at all to support this device.
It sounds similar to the DBox2 or Firewire recorders. While I wouldn't
recommend modeling your code after those, it sounds like all you need
to do is implement a DTVRecorder child class and a ChannelBase child
class for your device along the lines of those two recorders. There is
major/minor channel and "freqency id" and program number support in
ChannelBase.

But if you want to write a driver, DVB probably makes the most sense.
Though V4L has no problem with MPEG4 streams.

As for developer docs there are some at:
  http://www.cuymedia.net/doxygen-dev-docs/html/

These are generated from the code, which you can do yourself by going to
the mythtv/docs directory and typing "make devdocs". That would generate
some more up to date docs. You will need doxygen installed.

BTW I'm always looking for doxygen documentation patches...
