This series is a show within a show
This is why it's called the Scooby Doo Show. Scooby Doo Goes Hollywood is the real life struggle of Scooby wanting to leave a show, this show. The Show within a show in Scooby Doo Goes Hollywood is this show and not Scooby Doo, Where are you?
The two shows are closer in age and the title of this show seems to imply it.
