philmottin said:right and wrong...
you are right cuz its not a lag actually...
not just because isn't a internet connection it means its not possible...
in fact it happens and its called DELAY.
LAG is just the internet slang for delay...
long cables always have delays, even the electricity's cables...
well .. it's short for latency.. it's the same for internet connections and tv signals, but on tv u usually wont notice it, cuz..well u dont have anything to respond with, except when, in this case, u have a console hooked up to it..
About tvcards; there are some that have a little lag. it's usually because it has some processing of the signal to do among other things..
