Interesting attitude for a new member asking one of the more generic questions ever asked, and didn't make sense the way it was asked in the 1st place due to the complete lack of any detail of intent, use, etc. That attitude is a perfect way to be completely ignored on down the line.
OP: in the future it might be nice to explain what you DO know, and what you DON'T know rather than expecting everyone to read between the lines. Believe it or not, that 3 word "question" has been asked before by someone that seriously thought that all they needed to do is bring a cable box and it would work. Don't put yourself in the catagory.
