G'day from Oz

Sounds like iTunes has been set as the default player, and the only way to stop that is to set another player as default.

I'm not sure, cause I haven't tested it, but try opening QuickTime, then menu

Edit/Preferences/QuickTime Preferences

Then scroll to - Browser plug-in
and tick - Play movies automatically

This might have more chance of working if LimeWire is running, but I suspect it will only effect your nominated browser.

I haven't seen anything in LimeWire that lets you set a default player.

The other way is to re-set the creator code of the files as they are moved into the download folder, using Applescript. I've written a folder script that does exactly that, but it needs some cleaning up. You are welcome to it if you have problems.
