r u  sure that your connection isn't poor?

If the connection is degraded, realplayer will just jump from scene to scene instead of buffering and playing. I'm not sure why that is, its definately a setting in the options that could change that and make realplayer, wait, buffer, and then play.

I would try to find a site that you know has respectable bandwidth and try to view something on their and compare the picture quality w/ the other site you are complaining about.

Good luck.
