Ah - thanks for the calc!

So, I tried 778000000 and bingo - we have services, well...

0x0000 0x117f: pmt_pid 0x117f BBC -- BBCi (running)
0x0000 0x123f: pmt_pid 0x123f BBC -- CBBC Channel (running)
0x0000 0x1081: pmt_pid 0x1081 BBC -- BBC TWO (running)
0x0000 0x1041: pmt_pid 0x1041 BBC -- BBC ONE (running)
0x0000 0x10ff: pmt_pid 0x10ff BBC -- BBC THREE (running)
0x0000 0x113f: pmt_pid 0x113f BBC -- BBC NEWS 24 (running)
...

Well done that man - thanks Will!

Surely there must be a utility (in the making possibly) to take the "choose a transmitter" out of the user land, set top boxes do not require this level of knowledge (although I feel empowered now I see the math) ;-)

Thanks again,
David.
