i've found 375kbit/s video with 64kbit 44.1kHz aac audio is the best it'll play smoothly, that's at 25fps. Don't use 2 pass though, you need single pass encoding so the bitrate is constant.
I've been playing a lot with different encoders and bitrates since i got the phone, so i'll be writing up a guide for top quality w900 video conversion in the next day or so.

Thanks Mysh, i'd kept having sync and stuttering probs on some vids and now i know why! two pass has better quality but i'd rather have a smoother video at the expense of a little quality

Hi there, I have just bought a w900i and its having problems playing mp4 files downloaded from the web. They simply judder, skip, freeze and lose the sound. However, If I re-encode them using 'ImToo' at 350 kbps video (320x240) and 32k audio, they play ok. Do I have do do this all the time or is it a known fault with the phone? Does this phone require a firmware update? If so how do I do this? Thanks Lee.

about 380kbps video bitrate is the best without skipping any frames, but if your clip is longer than 15 minutes, you need to drop to around 250kbit. There's some kind of buffer problem, after 15 minutes 380kbit will begin to stutter a frame each second.
The guide i was posting is slightly delayed. although nero recode / mpegable x4 give very good results, i found an mp4 muxing program that gives exceptionally smooth playback on the w900i, incredibly good really. But it has some audio sync problems that i'm still trying to fix. Once i find the problem i'll write up the howto, you'll be impressed with it.

i'd be really interested to hear how you get on playing a full movie on your w900i. I'm having some real problems with mine, see this thread -

Edit:
Are you using the walkman player, or the file manager one? Also are you playing the videos from an MS Duo card or from the phones memory? I'd really appreciate some help figuring out why i get gradually stuttering video playback on mine, thanks.
