Watch, pause and stop during streaming

[francesco75]

I'm wondering if there is any way to stop, pause and rewind live events like what it'spossible to do with any kind of Media Center. Expecially when I'm watching streamed events it would be nice if It was possibele use some kind of dynamic buffer to put in pause what I'm watching.
There is any way for doing that ?
Sorry for my english and thanks for yours help.
