I got arround this problem by making a minor patch to the mythvideo system.
I don't think this patch has been applied to the CVS tree, however.
I have attached my patch, if you want to try it.
My original message said:
I have some videos which are 16:9 and some which are 4:3. These videos
may be mpegs or avis.
This patch causes mythvideo to look for a ".mythvideo" file in the
directory where the video file is located. If that file exists, the
content will be used as the player command instead of the default.
For example, in the directory where I keep my 4:3 video files, I have a
.mythvideo file which contains:
xrandr -s 640x480;mplayer -quiet -monitoraspect 4:3 -framedrop %s;xrandr
-s 888x500
This changes my output resolution to 640x480, runs mplayer with a 4:3
aspect, and then switched back to my normal 888x500 (16:9) "menu"
resolution when mplayer exits.
There may be a better (more efficient) way to achieve this
functionality, but this was a simple change.
