Let's say everyone has plug-ins installed....Do you think they want to go see the same show everytime they come back.
I think what you have is awsome! But they say before someone makes a purchase they visit at least seven times. You have to remember your visitors are going to be connected some where between 24k to 33k and it will get old waiting everytime.
Your entrance page should start with a choice (enter here for our awsome Flash show or Enter here for faster service) and not start into the flash.
