i downloaded an Xvid AVI file which is seizure-inducing'ly "jerky" during every second of play-back on every media player (WindowsMediaPlayer9,WinDVD,DivX Player 2.1,etc)... do i need to re-encode/convert this file to another NTSC or PAL "format" in order to view it correctly on my computer, without the constant "choppy-ness"? ...or do i have to accept that it's a bad encoding job by the original DVD-owner? according to GSpot the frame-rate of this AVI file is 23.976, aspect-ratio is 512 x 384, codec is Xvid. the file was encoded from a 50-minute japanese music concert DVD, i think. i checked to make sure that my other Xvid-encoded video files and they all played just fine, but this particular file is jerky... do i need to convert this file to a PAL format or something?
