The number one message I receive is from QuickTime: "Additional software is required for QuickTime to play back this media. It may be available from the QuickTime Components page. Make sure your internet network connection is active, then click the Continue button to check for the software."

Is your LW properly connected (all green/blue connection bars)?
I don't see any green/blue connection bars.
Often I get this message: "The movie could not be opened - An invalid public movie atom was found in the movie".

I registered at BITZI but what is it all about? I'm not as advanced as you are in these matters.
