nobody has a preferred codec that seems to work well?

just render something at as near 480 x 800 as you can.
If the video is larger and the screen can't display it, why waste CPU/GPU on it?!

depends on the bitrate and/or profile you're using. the MPEG-4 codec works for me, next best thing to H.264 (which is supported but only the baseline profile, plus its more cpu/gpu intensive)
i use Handbrake and convert all my HD stuff into 800x448 using the MP4 codec at 90% quality with stereo audio mixdown. works brilliant on the N900, never stutters (even though i havent overclocked). max file size should be less than 4GB tho.
hope this helps.

You want to try out sharing your videos via your windows media player and then windows automatically converts/streams them on the fly over the network to the n900 at top quality without messing around with conversions, an icon appear in the n900 media player lower status bar area 
PS3 can also play such videos without need for conversion

What I would be interested, is the codec and settings which is most efficient (quality/size) but is still optimized to use other processors than just CPU (so would use GPU and DSP).
I would not use H.264 settings which would make it non DSP-optimized. Same thing for audio. I'd love to use OGG Vorbis, but currently still I think , vorbis decoder is not optimized for DSP like MP3 and AAC.

I believe h.264 and aac are hardware accelerated. I don't have my device in front of me, but you can look at the libraries, the filenames will show it

well, this sounded good:
http://hacks.mozilla.org/2010/04/theora-on-n900/
i have no idea how it compares or if it's even available

The resolution is set to even slightly below the N900's native resolution. It's not a res problem, but a codec problem. Thanks anyway.
