Just how big a load are UDP broadcasts?

I run a small network of small sites, including a couple in the
Adirondacks with 56k feeds. When a user of one of these sites uses
one of the UDP audio or video services it drives the 56k to 100%
saturation (load 255/255) and makes the site unusable for everyone
else.
Recently I "solved" this problem by blocking this traffic at the entry
port for my T1 feed. To my surprise, both the average and peak
traffic on the T1 dropped by a factor of 3, although less than 2% of
my users complained.
Traffic on my T1 wasn't the issue, but this has me wondering: how much
of the Internet congestion my users do complain about is due to UDP
audio/video services?
In my very limited view of the world, UDP is a very poor network
citizen among protocols. Am I wrong in that view?
