I'm a beginner to all of this so here is a dump question...

What is the difference between RealMedia File and RealPlayer File. I have two video clips in RM format. Apparently, one is RealMedia File and one is RealPlayer File.

I can open RealMedia file clip in MetaEditor and do the cutting and editing to this clip. However, the other clip that I have which is a RealPlayer File, I can't open it at all in MetaEditor.

Would someone please explain to me the difference? And how can I convert it to a RealMedia File? Thanks!
