For those without ESPNU here is a way to watch ESPNU on your pc:
You need to have both the VLC media player and Sopcast installed
http://www.videolan.org/vlc/
http://www.sopcast.org/
Once you have both programs installed:
Open this sopcast stream: sop://broker.sopcast.com:3912/22668 (can do this in a new browser [at least on firefox] by copy and pasting in the html bar)
Once you have a solid sopcast connection, open the VLC media player and go to File/Open Network Stream
Go to the network tab and enter http:// 127.0.0.1:8902 (without the space after http://) in the HTTP/HTTPS/FTP/MMS field
Click OK
Do not close sopcast once the feed starts in VLC.
