[mythtv] xinerama kludge

[Fletch]

Just got everything going on my RH8 box yesterday (fairly smoothly
once I got all the prerequisite RPMs installed), but when I actually
watched TV it spread the picture out across both heads of my GeForce
4400.  I came up with this quick patch which (along with the addition
of -lXinerama to the mythfrontend and mythtv make files) gets things
working on just the first head.  And I just now noticed that there
probably should be a call to `XFree(sinfo)' in there somewhere.
