hey guys im thinking about buying a capture card but i have a few questions about it. for anyone who has one whats the best to buy but also one of the cheaper ones cuz im not looking to spend hundreds on it also im using a non-hd tv so i only have the red white and yellow av but my xbox av has a seperate green, blue and red hd tv attached to it. can i still use the capture card with a non hd tv?
