Videos are choppy with FMS 2.0

I'm using FMS 2.0 to stream videos. It works great on my computer but a lot of people are complaining about the videos being choppy.

This is the web page - http://www.ncswlearn.org/components/videos/?id=33 Are the videos choppy for you? If so, how fast is your internet connection and how much RAM do you have?

Any other ideas for what might cause this and how I can fix it? Thanks! Any help / responses is greatly appreciated.

    What I was getting at is how much bandwidth is available at the server. Let's assume the server is connected to the internet via a T1... that gives you 1.5mbps. Let's also assume the video is encoded at 500kbps... that would mean you can only support 3 concurrent viewers at a time before it runs out of available bandwidth. When the 4th viewer connects, the server's bandwidth will be maxed, and video will get choppy for everyone.

    Video plays smoothly for me. My connection is 20Mbps, and I have 4GB Ram installed on the viewing machine.

    I wonder... when you get complaints of choppy video, how many viewers are watching? Are you maxing out bandwidth at the server perhaps?

    Thanks Jay for testing it out. There aren't a lot of people who view the videos, so it's unlikely that more than one person would view a video at a time. I'm going to take home the slowest laptop that we have in the office tonight to see if computer speed or amount of RAM has anything to do with it. One of our users even said that they were on a T1 connection and the video was still choppy. Seems kind of odd to me.
