How long does a channel have to be dormant, i.e. without a channel change, before Cox throws up the automated "this channel is now blank due to inactivity" screen, 4 hours - 6 hours, 8 hours - what is the current time interval?
Is there some way I can turn off this feature? I frequently leave my tv on a single channel in the background and really do not like having to retune it when the music comes on.
