I need my visitors to be able to right-click and 'Save Target As...'

Hi I wonder if somebody could help me with this one. I have an all-flash site and there is alot of audio (MP3) and video (WMA) on there. My visitors have been moaning because the media will only stream for them and they cannot actually download it easily. When a stream button is clicked Windows Media Player launches after _blank. If they right-click then they get the Flash player menu only!

Is there any way which I can make my site so that they can right click and save the media to their PC similarly to if they were on an HTML page?

Any help greatly appreciated.

Jay.
