To make AMV's one of the ways to do this is people use some kind of device which they hook up to their TV and use it to record their games and Movies, and then they can upload these to their computer and use a programm to edit them am I Correct? So what is the Device they use to record, How much does it cost, and Where can I Find one?
I'm not sure what an AMV is, but what you're looking for is a device called a "Capture Card" They're fairly straight forward to find and use, and they cost anywhere from $40-700. Be warned though, the cheap ones usually don't record at very high quality. There's a list of them [COLOR=teal]here[/COLOR].
