Most of my movies when scaled end up as 800x336 due to the original films 2.35:1 aspect ratio. If I have a 16:9, I would do 800x448, being closest multiples of 16. As for throwing away vertical data, the whole movie is usually being resized, I think its a decent tradeoff.

Because we are dealing with mobile (battery powered) device, the optimal resolution may indeed push towards multiple of 16s if it enables more efficient decoding with CPU and DSP.

I do not know either details enough, but sounds reasonable to have 448 as a vertical resolution because it is multiple of 16.

Would be interesting though to get real world data of decoding 800x448 vs 800x450 in N900 and monitor the decoded session with powertop.

Ok. I am miffed. I am downloading uTube videos on my PC and wanting them to play on the Nokia N900.

What is the definitive codec or resolution that I should be used to avoid the dreaded "cannot play media format" error?

I just want either a PC program or method to simply be able to port MP4 videos to the N900 without hassles. So far I think the issue comes down to video resolution size, as anything above 800 x 640 seems to be rejected. Is that true?

Is there a simple way of porting videos to the N900 without dread of coder hell? What should I be doing please?

UPDATE

It's all here baby!!
