Re: TV Remote
I have a Master/Slave power boards on my computer and stereo system which turns everything off except the master device.
For example on my stereo/tv setup once the amplifier is turned off the power is completely disconnected from the TV, PVR, WD Live, Bluray player, network switch, powered speaker system etc.
The obvious advantage is that instead of having 6 things on standby you only have one but you don't have to scrabble about to the find the switch when you want to use the system.
When the amplifier is turned back on then all the devices on the powerboard are turned on.
My brother was impressed by it and bought one when he got back to the UK. He said they are not as common as here (where you can buy them in the supermarket) and he had to shop about to find one but they are not that hard to find.
