I _think_ this is fixed in current CVS. At least there was a lot of activity 
around this code a little while back, and after some problems, it seems to 
work here on both 16:9 and 4:3 targets, and last time I checked, windowed too.

FYI I am using Xv output. There are a couple of setup options related to this, 
so that may also explain the different behaviour.
