Quicktime automatically adding file extension?!

I use Quicktime for all my video playback - so i'm assuming my problem lies with this?

I do VJing and when I'm downloading video clips (non-mpg4) i.e. avi, flv etc - the downloaded files are adding a '.mpg' extension onto the file - so that it wont playback automatically in quicktime. For example a file downloaded called '1234.avi' ends up in my download/desktop folder as '1234.avi.mpg'?

The problem means I have to manually alter each file name deleting the .mpg file extension (and confirming each time that I want to change it) - so it will load in quicktime. I'm assuming it may be because I have ticked the box on 'always open this file type with quicktime' - which is what I want, but how do I stop it adding the file extension each time?

Duo core intel 2.4Ghz iMac & MacBook, Mac OS X (10.5.6), iPhone, iPod video

Quicktime has nothing to do with downloading files with a web browser in terms of adding extensions to it.

You can disable that confirmation dialog in finder by the way. It is annoying.
