I see that you said .m4v files are supported. While I agree they are supported from the standpoint the N800 opens them and tries to play them, it's not doing a very good job with the files I have. Some will play but are EXTREMELY choppy, while others will make it hang completely. The files I'm trying to use are either those which I encoded for my iPod, or those that are available as video podcasts like The Discovery Channel.

I guess it could be a problem with the encoding settings being too high, but it boggles my mind that the iPod can play them well while the N800 chokes.

For my personal movies, I *can* re-encode them to something that works well on the N800 (xvid, 560x330 @ 24fps, 700kbps, MP3 works VERY well), but I'd rather not have to go through that if I don't have to. For video podcasts, there is nothing I can do... it will be whatever they encode it for, and iPods are king right now, so that will be the de facto format for most I would think (hopefully that changes to something like xvid AVIs.

Any help in figuring this out would be GREATLY appreciated.
