You can easily setup the 220 to run 2 separate xscreens - 1 on hdmi
and 1 on vga.  You can create 2 buttons on your remote that restart
mythfrontend assigned to the proper DISPLAY value (0 or 1).  Then you
never have to mess with geometry settings, etc and mythfrontend will
automatically scale properly to the display in use.

I don't need anything very special, just a video card which has standard VGA and HDMI or DVI port out. If they can work simultaneously, great, if not, not a big deal if I can switch between outputs from the GUI.

Kinda depends on what I end up doing for that final output, the head end we're talking about.

Eventually, I'll upgrade some of my TV's to HD, at that point, I'll care more about getting proper looking SD along with HD on those TV's.

If you are going to modulate it, then obviously this is all moot  :)

I can almost assure you that a piece of equipment that will modulate
multiple sources and put them on the wire for a "tuner" to receive
will cost more than putting an ION based machine at every TV and using
that "rf ready" cable for ethernet  to talk to the single mythtv
backend.  :)
