OK, a bit more *on topic* than of late:

Two things happen with my bedroom setup smack on 3 am: The standby light on
my little digital telly starts flashing to denote that it is downloading the
EPG and at exactly the same moment my FM tuner/hifi amp goes very quiet (but
not completely silent). It goes back up to normal when the light stops
flashing on the telly. Both the tuner and the telly are connected to the
same (Denon SS) amp at 'line level' otherwise there is no communication
between the two bits of kit.

Anybody got a clue what is going on?
