nokia video converter won't run on vista 64 bit so i use winAVI mobile converter to encode .avi into .mp4. no stuttering, no artifacts, and you can skip through the video with no hesitation of the picture.

settings i use are: 400x240, 512000 bitrate, 64000 audio bitrate, 29.97 fps

so anyone unable to use the nokia converter, or you want to use the built in media player to watch video i suggest trying winavi mobile converter. it can create great .3gp for nokia mobiles as well!
