 I run the GUI at 960x540 (which is the highest resolution I've found a
 working modeline for my TV for), then switch to 720x576 for watching
 recordings (PAL TV, so there's no scaling).  This worked fine with 0.21
 but I now only get part of the picture - it's been scaled up (probably to
 960 pixels), then  the right-hand side is cut off.[[BR]]

 I found an old post reporting the same (or a similar) issue
 (http://www.mailinglistarchive.com/mythtv-users@mythtv.org/msg99689.html)
 but that didn't seem to reach any resolution (he switched to VDPAU which
 didn't have the same issue).  He also didn't see the issue with LiveTV,
 whereas I get the same problem with both LiveTV and recordings.[[BR]]

 I've tried digging into the details but I can't make sense of it - a lot
 of the code seems to be working with the Display dimensions vs Video
 dimensions for scaling, but the Display dimensions are never altered from
 their initial settings.  Should these not change when xrandr alters the
 display?  I've tried resetting them there but it doesn't seem to help -
 it's still picking up the wrong dimension at later points.[[BR]]
