Video aspect override: Off
Zoom: Off
Video Playback Profile: Normal
Vertical and Horizontal scaling: 0
Scan displacement (X and Y): 0
Video Aspect Override: Off

In Appearance->Screen Settings I have tried setting Monitor Aspect Ratio 
to 16:10 and 16:9 with "Use GUI size for TV playback on and off.  These 
settings seem to have no effect, whatsoever.

Nvidia driver finds the monitor, sets the resolution/refresh just fine 
with no Vertrefresh/Horizsync settings specified (uses EDID).  My old 
19" CRT monitor worked the same way.  There's no problem getting the 
resolution.  The problem is that Myth is filling the screen instead of 
putting black bars top and bottom.  Xine and mplayer work as 
expected/desired.  It's as if Myth is trying to be "too smart" for its 
own good and filling the display by stretching the video vertically 
(people are tall and skinny, round things are oval).   Same settings 
work fine on my HTPC PC, FE/BE, connected via 15-pin analog to a 37" LCD 
monitor/TV but it is 1920x1080 and doesn't distort the picture the way 
it does on the remote FE computer with the 1920x1280 display.  I'm 
wondering if there's something in the backend (with the monitor that 
matches the content) influencing the remote frontend's ability to 
properly scale the video.  Any ideas?  Or should I submit a bug report?
