Hokay, let me first say thanks to divingmule and everyone else pushing this project forward. I think IPTV is the future and it only makes sense that our favourite media centre application should be ready to go!
However, I have found one problem with the current system... I think.
I'm into Starcraft 2 and in particular watching professional streams over at twitch.tv which is a subsidiary of justin.tv. Justin TV has made the decision to move pretty much all of their SC2 streams over to Twitch. At first you wouldn't think that this would be a problem but it seems that if the page is redirected to twitch.tv the plugin doesn't read the data correctly.
For example: if one were to go to
www.justin.tv/Ogsvns your browser will redirect you to
www.twitch.tv/Ogsvns
If you search for Ogsvns inside the plugin on XBMC (provided he is streaming) it simply won't work.
But for some games that have not been exclusively moved to twitch.tv (and some channels like ign proleague) they can operate under the justin.tv/username or twitch.tv/username guise...
And it works in XBMC like a champ!
I have included some examples in this pastebin

Some info about my setup:
Ubuntu 11.10 32bit
XBMC Eden RC2
Justin TV Plugin 0.2.5
rtmpdump ver 2.4 (compiled on this system and dumped librtmp.so.0 in the right folder, couldn't make it work at all before this.)
