just out of curiousity, what resize algorithm does xbmc use for video playback?
default is a bilinear filter.

thats what i guessed since bilinear is the fastest resize algorithm and xbox is limited to a 733 mhz cpu.
but still it would be nice to have the option to change re-sizer from default bilinear (acceptable quality, fastest) to *bicubic (high quality, slower) in the post processing section.
would be really nice especially for those with sharp tvs. http://www.xboxmediaplayer.de/forums/non-cgi/emoticons/wow.gif
well i don't need to tell you that there are a bunch of open-source programs which have the re-sizer(s) simd optimized like ffdshow (http://sourceforge.net/projects/ffdshow/)
(you can probably move this thread to feature suggestions) thx *:lol:

actually, i'm not so sure about this.
we use hardware overlays for video output, thus all scaling is handled by the xbox hardware - the surface that we draw the video into is the size of the source video. i'm not sure whether this uses the same filtering that normal textures etc. use.
perhaps a directx guru could let us know more?
