Thank you for your perseverance mark416. It seems to be a problem with the ExcelCalcs Player. I have just installed the latest software this might be better (but that's a long shot). The following files are in a different format.
Can you play
video in flv format?
Can you play
video in wmv format?
I suspect you will have a problem with the wmv format. I tend to use this the most because I get better compression from it and they maximise very well. Failing this I can upload to our
You Tube Channel.
