How to change size of movie in safari when opened with QT?

WHenever i open a movie online, and stream it... I want to be able to double or half the size... how can i do this?

Can i not use QT? can i use VLC instead also?

Thanks

 

If you are asking if you can make someones webpage, display an embedded movie larger, your nuts. The size of the window for the movie is hard coded into the web page there buddy. You can open a movie in a QT window and just drag the lower right corner to the size you like. Or download the embedded movie, then make it bigger while watching it with QT.
