I might be wrong but I got the impression that at least some of those "motion detection" programs are geared more towards "change in frame" - i.e. if the current frame contains exactly the same info as the previous one then toss it. It saves both space/bandwidth (e.g. the English guy who caught a burglar a few years ago by streaming webcam over the net from his apartment) as well as your time looking for the interesting frames. --Amos
