Er, no. If your system is on but sitting at any menu I guarantee that it will be 
using a great deal less power than if it is decoding a video and displaying it. 
I would even venture to suggest that running an SD video consumes far less power 
than running an HD video (video = recorded material of some kind).

Even the bit rate/frame rate is going to make a difference to the power 
consumption. You can't say that it is an all or nothing proposition.
