I plan on doing (among other things) animation reviews on my YouTube channel, but in order to be the channel I want to be, I need to be able to play clips of what I'm reviewing in the Review (I will keep things within legal/fear use boundaries, and only show what is needed), so I need a capture device, but it's hard to know which device I need, so I have uploaded a video for you to see, which shows the kind of television I use, among other possibly important things.

I also plan on doing gaming videos, but I don't know if I can get away with putting my capture device in my TV for this as well, or if I need to attach it to my console.

Please answer as soon as possible, as the sooner I can do this, the sooner I can become the YouTuber I want to be, but if anything isn't clear about my question, please say, and I will try to explain further.
