Using tv as my computer monitor

you're referring to "switch the preset" what does that mean? if you're already using the tv as the monitor I'm not sure what you're trying to by switching it to something else.

What do mean by capture video from your 360? your tv should have no trouble displaying 360 output if you've connected it properly and switched the tv to proper input source.

If you're trying to do something else, you've done a poor job explaining it. So in order for someone to be able to help you we need to understand what you're trying to do.

ok, I'm still confused a bit so let me try to lay it out.

you have 1 tv that you're using to as a pc monitor and as a screen for your xbox360. Both pc and xbox are connected to the tv via different input ports. I think we are ok up till here.

you have a video capture card that is connected to computer, I guess? if not, can you tell me what make/model capture card you got so we can be on common ground?

if you got the capture card in your computer, how are you connecting the xbox to the capture card?

the tv cannot pipe the signal from 1 peripheral to another.

typically you will have the capture card connected directly to the xbox for input.

If I'm missing some piece of information, please let me know.

I am a bit confused myself, but if I understand you correctly you are trying to output from the Xbox with HDMI and component cables at the same time.

As I understand it the Xbox won't (or didn't used to at least) let you ouput video from HDMI and component at the same time.

Edit: Assuming that hasn't changed you would need to go from your Xbox to your capture card in your PC and then from your PC to yourTV/Monitor.

if your using a black magic intesity pro, you will need to unhook your xbox from your computer for a min go to your settings on your xbox and set it to 720p. This is the highest standard that the black magic will be able to handle. Don't worry it still looks great.

then go ahead and reconnect your xbox to your computer and your computer back to your tv on a hdmi imput. This should solve your problem. I will keep monitoring this thread if you need any other help, with either recording your gameplay or streaming it live on a site like twitch.tv.

hope this helped
