Ok, Kirk and I have gone through all the lessons and resized the newer ones that needed resizing so that they can be seen embedded in Firefox.
The problem was with Windows Media Player 11 and Firefox and the video sizes.
You will notice that some of the older lessons with videos are now shown in a smaller video format like the example below as they were originally saved at a smaller size. I have now also added a link underneath all the movies so that the movie can be opened in Windows Media Player directly as well as having it playing in the embedded page... you can then resize it there.
If anyone is having any issue with the viewing of the movies, please let me know... and if you could also include your operating system, the browser version and the Windows Media Player version you are using that would be a great help.
Cheers
Clancy
