PROBLEMS WITH DOWNLOADS.
Using Mozilla Firefox:
I had no problems downloading the Lecture Notes, but downloading the videos resulted in a screen full of gobble-de-gook. (Random Ascii characters to the initiated).
Save these odd-looking (video) files with the .wmv extension.
Click/double click on the saved .wmv file to activate it.
Windows Internet Explorer:
IE seemed to recognise these video files OK.
