Hi nb1,
recent hype over standby modes and the power consumed is somewhat exaggerated. Some things, like your vcr, digital microwave or digibox need continuous power to maintain the system clock and your personal settings. Most have an internal battery that allows them to cope overnight or during a power cut without losing this info. Yes, you can save power by switching things off at the wall (unplugging is not necessary) but it really is rather minimal. Try reducing your central heating by 1 degree and you will save far more energy.
The vast majority of energy that is consumed by devices on standby ends up as heat, so in the case of the upcoming winter, if your tv, vcr, dvd, etc etc are all using a bit of power, and dissipating it as heat, this just means your heaters have to work less to keep your house warm. Summer is a different matter, of course.
I am concerned about the environment and am prepared to do my bit, but with modern electrical appliances standby power consumption really is quite negligable. I've seen hotels with burning gas decorative flames outside and many unorganised businesses with heaters and air conditioning on in the same room. This is the waste that needs to be addressed.
You should be able to find the standby power of any of your devices in the manual.
