Thank you all for your replies,

So I am thinking that, yes, it is live, but is looped for a ceratin amount of time? and that would be the reason that if you listen for let's say 1 hour, and then pulled it back to the start, then the transmission repeats, however if you refresh, then the live feed starts once again?

Sorry for being so blonde (no offence to any blonde's out there!) ... I dont usually get confused this easily, but boy! am having trouble with this one :P ...
