switching connections with equipment on
i realize it's a pretty basic question but after i'd switched leads (hdmi, rca composite and S-video) leads while components were turned on, i found a couple of warnings to not disconnect/connect with equipment powered up.
what is the risk or danger? - is it that critical?
tks in advance
