Hello, I've been testing video players in my N800, and mplayer is by far the fastest video player in this tablet. Now, I'm looking for the best video quality that mplayer can run smoothly in the tablet. Most of the topics in this forum discussing video encoding for N8x0 are old or are based on the build-in video player. So far, what I've found, is that I can play 640*450 without any lags. Container: AVI Width 640 Height 640/Aspect Ratio Video Codec: Xvid (with 1 pass) Video bitrate: 800 Audio Codec: MP3 Audio Bitrate: 128 This works like a charm even with subtitles, I'm looking forward to see what can you get from the N8x0 processor.
