I bought an audio/video input for my macbook which is for recording. I got it to work fine, however, it gives me a tiny screen to work with and it only works if make it record. So my problem is I want a program or just find a way to switch my screen to a video display. Just like the way you would on a tv when your about to play a video game. I found a program called BTV, but I had to install a bunch of other programs to go with it and it just became a big mess.

I used to have something like this for my pc and it was an actual switch I had to flip. I have a Pinnacle Video Capture (just to give you an image) so there's no actual switch. I just want something simple to go back and forth between video and my display. There has to be something out there.

Please, someone help me!
