Hi,

libddmpeg-1.7b works fine on my system both with and without the 
viaslice-reverse patch (I don't actually see any visual differences after 
applying the reverse patch).

When I set resolution to 1280x1024 switching into and out of live TV mode 
still throws the mythtv menus into "shaking text" state.  Watching a 
software-transcoded recording fixes the problem.  Lower X resolutions do not 
show this problem.

I would actually prefer to run in 1280x1024 because it is an LCD screen and at 
lower resolutions the mythtv menus have a bad case of jaggies.  Using xrandr 
to switch into a lower resolution mode during TV watching seems to work ok, 
but when I switch to watching a video using mythvideo, the fullscreen video 
is reduced in size to the lower resolution.

Again, thanks for all the work on this.

Lincoln
