I just came across this great resource.  It is full of creative commons media - that's film, audio content and books.  You could download old classic radio episodes and listen to them on your media player.  You can legally download all the media in a variety of formats depending on your connection speed and how much resolution you want.  I suggest you download the MPEG4 file and use VLC or mplayer to watch it.

Ian you should definitely take a look here.  There is a vast range of content so take a look.
