Media URL/file handling question - downloading file vs. passing URL to player app?

Hello,

I'm running Mozilla 1.6, as well as Firefox 0.8, on a MacOS X 10.3 
system. The behavior I'm describing below is evident in both browsers.

I've noticed that different media types are handled differently under my 
system depending on the player that the media is associated with. I have 
the three major media players under OS X (Quicktime, RealOne Player, and 
Windows Media Player 9) installed.

If I click on a URL that points to a .mov or .mpg file, handled by 
Quicktime, the player is embedded in the browser window, and begins 
playing as soon as a sufficient buffer is loaded given the media size 
and download speed.

If the URL is to an .rm or .ram file, the browser downloads the entire 
file, saves it to the desktop, and then launches RealOne to play the 
media file.

If it's a .wmv file, the browser passes the URL to Windows Media Player, 
which handles its own buffering an playback of the file in a standalone 
player window.

My question is: is there any way to conrol this? There are times where 
I'd prefer to load the .mov in its own browser window (in order to zoom, 
for example), or to be able to play an .rm file as it loads, not have to 
wait for the entire download to complete (in both cases, selecting "Open 
Location" in either player's file menu and pasting the URL in 
accomplishes this goal). If there isn't a way to do this currently, hwo 
does one put in a feature request for a future version of Mozilla/Firefox?

Thank you,
