I know the N900 has good potencial and alot of capabilities, but i'm wondering what everyone is throwing at this device video-wise. I managed to play alot of stuff that i have out of the box with the default player (many mp4, divx, xvid files). The highest quality video i made it play so far (without lagging) is this: Name: Avatar.Trailer.2.avi Duration: 3mn 30s File size: 80.7 MiB Format: MPEG-4 Visual Codec ID: XVID Resolution: 800x480 Video Bitrate: 2 981 Kbps Audio Format: MP3 Audio Bitrate: 224 Kbps Sample Rate: 44 Khz The picture quality is really HD-like on the N900...I encoded this from the 1080p quicktime file. Post your results !!!
