ustream.tv ...and, streaming reliably from it using windows command-line

I am currently using the below website to convert a "friendly" ustream.tv URL to a fully working rtmpdump.exe command-line.
http://piscui.webear.net/ustream.php

For example, this:
http://www.ustream.tv/SouthwestFloridaEagleCam

will produce:

Code:

rtmpdump -r "rtmp://ustreamlivefs.fplive.net/ustream2live-live/" -y "stream_live_1_1_12034538" -s "http://static-cdn1.ustream.tv/swf/live/viewer.rsl:96.swf" -W "http://static-cdn1.ustream.tv/swf/live/viewer.rsl:96.swf" --live --quiet

Here's the problemL: between yesterday and today, the URL changed by one character: Yesterday, the URL used in RTMPdump used to be:
rtmp://ustreamlivefs.fplive.net/ustream3live-live/

I'm curious if anyone has experience working with ustream.tv; and, know how to accommodate a change like this in Windows command-line. Im hoping there's already a Windows command-line tool that can help assist streaming ustream video streams to file.
