How to increase buffering?

Dear All, I am happily able to watch the videos on http://channels.netscape.com/ns/music/vidoes/archive.jsp?cat=f, however I would like to be able to increase the buffering so that I can view the entire video. Now, it plays a short while, stops, then resumes. This happens about 4 times or more before the video finishes. Does anyone know how I can increase the buffering? I have Suse 8.2 with a large harddrive and over 500 mbs of memory. The realplayer that is on the site works great on my system other than I cannot play all of the video all at once. Any help will be appreciated. Thank you, Marcia
