Just me again quickly as I don't know if it would interest you but I've been watching sport streamed online - here :
http://www.myp2p.eu
The way it works is basically ..
Click the Live Sports tab > choose a sport ie Baseball > choose a match and click the small tv icon on the right where it says watch live.
To get the streams to work you will need a compatible media player ( you can download them all from the same site - and all should be virus scanned.)
So say you want Boston Red Sox v Atlanta Braves you will see a list of streams with the media player indicated on left side ( I use Sopcast.)
So far I've watched live boxing from Vegas, football from all over the world, as well as cricket.
People are hooking up their Satellite Decoder to the PC and streaming the broadcast online.
Check it out if you like.
There are also help forums if you have any problems getting it running.
Talk to you sometime.
