Technically speaking the composite input actually uses *less* of the tuner than the RF input. It's one less pipeline stage. However there's nothing that controls power to the RF section so I would expect the power draw to be no different.
On the whole the mpeg encoder chip is probably drawing the majority of the power anyway, so any difference in whether or not the RF tuner is actually doing any work probably makes no difference at all. If there's any difference at all, I would guess that a clean (i.e. no video noise) signal would probably present less work to the mpeg encoder and so might lower the power draw overall - which would suggest again that the composite input would be an improvement over RF since weak signals / interference / other sources of noise wouldn't get in the way. But that's really just a wild guess. -Mike On Wed, 28 Aug 2013, Gary Buhrmaster wrote: > On Wed, Aug 28, 2013 at 7:50 PM, Lorne Shantz <[email protected]> wrote: > > Hmmm... so you think it is drawing more power to pull the signal from the > > vcr machine?
