You need to list the largest mode first.

The code to do so is in 0.13 -- that's what's causing problems with
Xinerama currently. Also, the text in the GUI is really tall and
skinny -- but worth it to me for the extra video quality. On my (long)
task list is the ability to use a different mode for GUI and video.
You absolutely have to turn on deinterlacing with this or you get
really weird artifacts on the screen -- which is a shame, since we then
go ahead and discard that extra resolution, but keep the resulting non-
smooth panning and ghosting that result from the simple deint filter.
The new kerneldeint filter is too CPU-intensive for HDTV. What would
be ideal for this use would be a 'bob' deinterlace filter -- simply
double each line in both fields. This is also on my long list, but
I've never dealt with YUV data before so it would involve a lot of
learning for me.
