OK guys, yet another newbie question. Why would you / do you need a remote to go with your TV tuner card? The extenders come with remotes to control them right? Do the extenders allow the ability to watch live TV via Sage (TV tuner card)?
To finish up the question (Collin answered the first part) - yes, with Sage extenders, you can watch live TV - although it's not really live - it's delayed about 5-10 seconds (it's recording it to the hard disk and then streaming it to you). If you are an avid channel surfer... this is a bad solution for you. It takes 1-5 seconds to change channels (depending on if its a STB or an antenna, HD, etc).
I never ever watch live anymore. Its so easy to go into the EPG and tell it to record something - and then I get something to drink or whatever and then start watching. Of course, I have hundreds (best estimate is around 200 hours) of TV already recorded to watch.
