[mythtv-users] Recent aspect ratio issues - what I've found

[Neil Milne]

I did an update of a lot of my system stuff today, including the
latest X.org server (7.2). I also built the latest SVN on 0.20 fixes.

After firing up the frontend I found the aspect ratio was all wrong
for watching both Live TV and prerecorded stuff.

After a bit of digging around, I discovered that the frontend believed
my monitor to be a 4:3 aspect ratio display which was odd, since it's
always got the 16:9 ratio correct before.

I believe that the latest X.org is reporting that Xinerama is active,
even though I am not running dual-head on my box, so the originally
retrieved screen dimensions are being thrown away and replaced with
settings from the myth database.

I've put in a temporary hack into videoout_xv.cpp to permanently
disable xinerama, which fixes the issue, but I will do a few checks to
see if there is a flag or setting on the X server itself which will
fix the problem.

An alternative for those of you affected by this who don't want to
rebuild from source would be to set the correct Xinerama parameters in
the mythtv settings database - I think it requires the
XineramaMonitorAspectRatio setting to be the correct ratio for your
display.

Anyway, hope this helps others who have been affected by the issue!

Cheers,
Neil
