Hello,
nimbletv.com is not a very well known service, though a very usefull one.
You can watch US TV all around the world aginst a monthly fee. Biggest flaw of the service is, it's only available via browser and Roku.
I'm pretty sure it's possible to change.
Their system is pretty advanced, nothing I've seen before. When you watch a stream, a m3u8 playlist is being generated, which contains links to .ts fragments, all of this supported by a heardbeat jQuery system. I made a screenshot to make clear what I mean:
I've tried several scripts but non really helped, my goal to play such a stream in VLC or create a playlist for XMBC.
You can try yourself on their site, the free channels work as well as paid ones.

Hope you guys can help.
