I can't find an answer to this anywhere on this board or on the internet, although i admit I'm possibly using the wrong terminology in my searches but I've tried everything I can think of. Whenever I open a video file of any extension in VLC or DIVX player, I can simply skip ahead to any place in the video clip, but when I open a file in quicktime I can't skip ahead like that, it takes ages to 'buffer' fully before it will allow me to skip ahead. The only time i can skip ahead in quicktime is when I'm using a .mov file. Now I know that the native quicktime file extension is .mov but is there a way I can play other file extensions in quicktime without the delay of the 'buffering' effect before I can skip ahead? Thanks for you help.
