....what would it be?

XD

[nicoli_k]

For a plugin Justin.tv and script Navi-X. These are my two most frequently used.

[mcborzu]

Script-This one shouldn't count but the SVN Installer...I never used it until the article on the front page pointed it out...Super easy, super cool

Plugin?-Don't really use much, maybe Gametrailers since I'm dying for MW2 to come out. I've been watching those videos recently.

Since I am on Windows my pick is the Launcher plugin.

I'm using linux and my vote goes to the Launcher plugin too.
It allows me to run Firefox from within xbmc on my htpc. :-)

I may be a little biased on this, but my NFL Network plugin is great this time of year!

[Swifty]

Its got to be dink's IPlayer plugin

[esdubu]

gotta be another vote for iplayer, just for the fact i can stick cbeebies stuff on for the little lad!

Opensubtitles OSD, without a doubt.
And XOT Uzg, but that's mostly interesting for Dutch people.

if you have a newzbin and usenet account, the SABNzbd plugin wins hands down.

Video Devil is a close second
