You can use an HD capture card like
Blackmagic Intensity Pro or you can use a Personal Video Recorder
Hauppage HD PVR to record game plays in HD quality.
Blackmagic Intensity Pro can be connected to your gaming console over HDMI. Hauppage HD PVR does't support HDMI, so you can record from component video output with it only (which is an analog connection). You may also need to use a separate audio cable. See more details in the following thread:
Blackmagic Intensity Pro vs. Hauppage HD PVR
The above mentioned HAVA Platinum HD also records in SD. It record to MPEG-2, so it is compressed by hardware for you. Your computer may not be powerful enough even to record 720x480 videos (I'm not even talking about 1920×1080 videos), so it's nice to use some hardware like HAVA Platinum HD.
Screen video capture software requires you to have a powerful computer especially for record HD videos. I suggest you to capture using Huffyuv or Motion JPEG video codec first, and then re-compress your recorded videos.

I basically know nothing about HDMI and high definition.
From what I can tell, my Xbox is hooked to my 720p TV using component video (three RGB cables) and stereo audio (white and red cables; not sure what this is called). As far as I know, that is HDMI. Or rather the xbox outputs HDMI, and my cable converts it to component video and stereo audio. Am I on the right track?
I have a few questions: - Should I go with HDMI cables to go directly from HDMI output from my Xbox to HDMI input on my capture card?
- Just want to verify that connection on the back of my Xbox 360 is in fact HDMI. Is it?
 - I want to record some pretty crazy gameplay, and I do not want to play it lagged on my computer screen via the capture card. I want a capture card that outputs the single in HDMI (to use my Xbox 360 HDMI cables I am already using) to sent it back to my TV, in real time to play my game without any lag. No lag during capture is super important. I cannot stress this enough.
- Will any HDMI copy protection disable capture?

- As for Blackmagic Intensity Pro, it has an HDMI input and an HDMI output. You can connect the ouput of your xbox 360 to the HDMI input of Blackmagic Intensity Pro, and connect the HDMI ouput of Blackmagic Intensity Pro to the HDMI input of your TV / LCD screen (although the preview screen doesn't seem to work when connected this way).
Alternatively you can use a passive HDMI splitter from the xbox 360 with an HDMI cable to the Blackmagic Intensity Pro and an HDMI cable for connecting to your HDTV (however as Intensity PRO can handle this without any splitters, there is no need to buy one).
You can also use an HDMI to DVI cable for connecting to your computer monitor. You may also need an in-line HDMI amplifier. Or use an active HDMI 1x2 splitter instead of a passive HDMI splitter and an HDMI amplifier.
- Older xbox 360 game consoles do not have an HDMI connector.
- See item #1
This should allow you to record 720p gameplays and play games without any lags.
- You shouldn't have any problems recording games. As for recording Blu-Ray DVD, HDCP protection is used when outputting video via HDMI.
Blackmagic Intensity Pro doesn't say anything about HDCP, so most probably it won't be able to record such videos. But you can use AnyDVD HD, which allows you to play Blu-Ray videos on any device even if they don't support HDCP.
