Special thanks to ogdens and Jim_Hardin for their help and response.
I checked out the links that Ogden kindly provided and I learned some new aspects for creating slideshows, particularly on the music side.
Jim, I followed your very detailed link and similarly learned a lot, but unfortunately you were using chapters or portions of Video which sadly rather confused this increasing tired old fella!
About half way down your link you had a scene showing
New Project with Unlinked Button? And Movie 1-4
That structure looks like something I would like to have for a series of Slideshows.
If you, or anyone, has the time and patience to produce a simpler version for a Photo and music slide show I would be very grateful.
I would like to re-iterate that I have created many individual slideshows in the past but my problem is trying to save a group and then putting a series onto one DVD.
Thank you, once again
