Ray, just as a clarification, did you actually get MythTV running under the
fbdev setup with the mirroring using matroxset?  It would seem to me that
this will not work since myth requires xv, right?  i have a Millenium G400
DH and i managed to clone the monitor using the matrox drivers and
powerdesk, but as i said before, you still cant get video on the tv due to
it being unable to scale the image.  It seems like there are a couple ways
to actually mirror the image and get the desktop on the tv, but i dont think
ive seen one person yet say that they actually managed to get myth fulling
working with the tv out.
