[mythtv] Ticket #667: Fix OSD font width and height for non-4:3display, letterbox modes

I'm having exactly the same problem - since I did a dist-upgrade of Debian.
Stupidly I did a svn update at the same time, so I don't know which caused
the issue. I've got my dpi set to 100 x 100, and this is reported by
dpyinfo. I've reinstalled the nvidia driver, checked my xorg.conf against
older backups I've had. I've reinstalled various font packages: freetype,
x-ttcidfont-conf, defoma.

Again, it's the same - text looks fine on 4:3 programs, whether zoomed or
displayed in a 'pillarbox'?. When a 16:9 program comes on, the text goes
wrong. The characters seem to be placed correctly, but overlap because they
are stretched sideways (like they've been 16:9erized). I've looked at the
code, but can't see why this would happen. There seem to be a lot of aspect

I'm completely stuck. It looks like very few people (2?) have actually seen
this. It baffles me.

Hope someone is able to help

ok, i accept that is a configuration fault.
but i'm damned if i can find out what.

i've reverted to the radeon driver (from the closed source ATI one).
i've set up DisplaySize correctly. i've checked that if i change it,
then xdpyinfo shows the modification. however, the size that xdpyinfo
and xrandr -q shows is not identical to the one i specified.
however, no matter what size i specify, it seems to make no difference
to just about anything.

what really, really confuses me is that when i set the aspect ratio of
the displayed video to 4:3, the text looks fine. and yes, this is on a
1920x1200 laptop display (16:10).
i've set the kde panel to not grab part of the display.

i will continue to work on this
