Modifying a player to render the image to be rotated in the first place
shouldn't be hard, though perhaps any straightforward way to do that
would degrade cache behaviour? (A wild guess.)

Also, as re-encoding files spesifically for the Neo would be quite ok
with me, rotating at that point would be quite a workable solution also.
(I'll add that I don't necessarily expect the Neo1973 to play back
decent video and won't blame FIC if it doesn't, but I'll sure _try_
it ;)

Now this is excellent news. I asked before if the XVideo extension
present on the xdpyinfo output implied scaling support; apparently it
didn't, but even having full screen QVGA capability should aid

And yeah, do concentrate on the high-res UI for now, but great if you
can at some point provide code/info for the QVGA mode. And Keith getting
a p0 phone, that's a nice one too ;)
