Please just forget my previous post.
I was just too tired yesterday

BTW: with StretchRect, according to the docs, the resize SHOULD be done by the GPU already. That's why it takes much less time.
I compared it with a 1080i video and here are durations for the process:

StretchRect (whole image): ~ 500 ms
StretchRect (64x48) : ~ 15 ms

So the stretch rect with a resizing took significantly less time, which i think comes from the fact that the GPU does the resize and then transfers the data which is always the same wether HD or SD.
BTW: the stretcrect time for SD and resizing is nearly the same as for HD.
This also lets me think that the GPU does the resizing here.

I think i have a goot solution to solve the problems the other noted.
Will post an updated patch later today
