I'm pretty sure someone already has. Although you are wasting your battery life doing so as the screen is far from 720p in resolution and the N900 only has an SD output to TV.

It could easily do 1080p if you encoded it in a way that goes easy on the cpu (think mpeg1 or something). That would nonetheless produce huge files.
Or you could also make it choke on simple 480p, if you chose a complex codec (for example h.264) and encoded your stuff with a really high bitrate.

The N900's DSP handles the HW acceleration of h.264 so 480p should play just fine.
Ahem

please google some things before post, its not necessary hd video on a device with a 3.5 screen and composite video out. lets focus on more important things.

Archos 5 from last year has the 3430 and does 720p, but has a bigger form factor, heat sinks and metal case that also helps to dissipate the heat from 720p. N900 would have a rough time without similar design. Archos 5 gets hot running 720p, so N900 would go supernova
Perhaps a lower bit rate would be OK.

Thats strange, as my Samsung Omnia i8910HD does 720p that I rip from Bluray so I'm sure the N900 can too.

The whole 'can do Xp' concept is silly. It's a resolution. Can the N900 play back at least some oversize videos with that resolution ? Yes. It's just that when you say 720p, it's unclear what codecs are in question, what bitrates, what fps, what HD profiles, what sound codecs/bitrate, etc. If they say 'it does 720p' and then you drop a 20000kpbs 60fps h264 1280x720 video on it and it chokes it would be 'hey, but thats's 720p, you liars, it doesn't work !'
