I don�t have the luxury of a multi media classroom but I do use  

YouTube for song and music related lessons.

I�m not sure if you are aware of this but it is possible to easily

change the format of the video file when downloading, allowing

you to play the file in a PPt presentation.

With Real Player installed on your computer (it�s a free download)

whenever you play a file on YouTube a little window appears on the

top RHS of the video. The sign says download this video. On the right

(in this little window) is a little window pull down button. (arrow) Left

 click this button and at the bottom of the pull down, it says save this

file as. Left click on it and the save as window opens. In the save as box

at the bottom �delete flv at the end of the file name and replace it with

avi � mpg � or any other file type you�d like to save it as. It sounds long and

complicated but once you�ve done it once��
