[mythtv-users] How to Set Aspect Ratio?

[Drew Tomlinson]

I have a MythTV installation I've been running since 0.17 on Gentoo. 
Currently I've been running mythtv-0.20.1_p13783 from the Gentoo ports
tree and it was running fine.  However last week I lost 3 of 4 drives in
the system (I can't believe it either).  I replaced them with a new 500
GB drive and restored the OS and applications from backups.  The
recordings are gone.

Anyway, all seems to be fine except that MythTV thinks my display is a
4:3 aspect ratio.  I have a wide screen that is connected via VGA to
component converter.  I am using the exact xorg.conf file I was
previously so that should be OK.  Other applications look right and the
Project Greyhem theme looks right.  However when I play recordings, the
4:3 ones fill the screen and the 16:9 recording have black bars above
and below (letterboxed).  I have played with the aspect ratio settings
with the "W" key but the results are applied to the incorrect starting
picture.  In other words, if I stretch, the resulting picture is
stretched more than the original.  Or if I fill, the resulting picture
is still stretched.

Any ideas on what is borked?  I don't know where else to look.

Thanks,

Drew
