Well - I offer the idea of using the VGA output directly.  Here in
Europe better TVs have RGB input via the SCART inputs.  A simple
circuit allows to connect VGA output to the TV.

You then need a card that can do interlaced output and low
dot-clock.  The SIS driver for the Pundit works, for example.

I understand that in the US RGB isn't so common - sets have Y/Cr/Cb
inputs.  For an off the wall idea - why can't we just pretend that the
VGA R is Y, G is Cr and B is Cb (for example), and use a colourspace
transformation within MythTV to remap the colour space correctly.

Is anyone interested in trying this?  Billy Biggs?
