The problem is that X's DisplayWidthMM and DisplayHeightMM
(used in videoout_xv.cpp) are returning values that work out to be an aspect
ratio of 1.5(4:3 with 720x480 is not) and videoutbase.cpp doesn't take
into account situations where the source image is identical to the
current display resolutions. As such it is forcing a resize of the
video down to be 640x480 displayed on a 720x480 screen.
You might be able to get around it with by setting some of the setup
options relating to display size but I never tried that. If noone
else submits a patch I'll send in mine this evening I've been using
it for a coupel days without problems.
