and we are a graphics company, and thus pretty picky about the image quality, given it is our stock in trade.
EDIT: Here's what i'm using to rip old TV series (progressive PAL). 680x480 4.25/3 anamorph, ffmpeg, monophonic, noisefilter.
Code:
<key>PresetBuildNumber</key>
<integer>2009112599</integer>
<key>PresetDescription</key>
<string>Optimized to scale older progressive-scan DVD sources (video noise, monophonic) to N900 mp4 optimized format, stretched to 4.25/3 aspect ratio.</string>

EDIT2: N900 demo video looks pretty nice - here's what mplayer reports for it:
VIDEO: [MP4V] 800x480 24bpp 25.000 fps 3543.6 kbps (432.6 kbyte/s)
[V] filefmt:44 fourcc:0x5634504D size:800x480 fps:25.000 ftime:=0.0400

obviously i can boost the bit-rate sky high, but at what point will a mobile device of n900 calibre cease to be able to play it?

Still, MP4 needs an update on the N900, since some MP4s that play fine on the Droid do not play on the N900.
added:
This is a nice thing about Maemo compared to Android. Maemo for the N900 can get codec updates. Android can not, since part of the framework and Android is not going to add a bunch of codecs that will work ok for some chipsets and not for others.
Up to the phone carrier and the manufacturer to request a driver add-in. That does not happen with Android (accept maybe the Sony versions).
