Im a bit of a novice with this stuff, but the way I understand this, without investing a really healthy chunk of cash, you are limited to 480I for capture from most cards. Holo3D II with the HD-Aux board seems to be the way to go if you want to do that route.If you are okay with 480i then try this card.
HDTV Component Input Card. This one will take composite input from a D-Sub15 adapter from composite. I have a feeling you might be in for some sticker shock here. I was.
From the little that I have researched on this topic, much of the technology that drives the HDTV recording cards for computers is a nitche market. Typically that means much higher pricetags for much lower quality equipment. You can compare that to the regular NTSC cable recording cards specifically from Hauppauge which tend to run from 60 to 150 depending on if you want one tuner, two, or a legacy card. These cards I know from experience will take a regular NTSC cable source and turn it out into a 720x480 resolution mpeg file. It does an absolutly fantastic job, but thats all it can do. The current DTV/HDTV standard isn't quite mainstream yet. Once it becomes mainstream and more people are interested in recording HDTV formats there will come a demand for HDTV cards. These cards will be able to take in a native 1080i or 720p record or even playback to and from your computer without using precious CPU cycles. Currently the only existing HDTV recording cards avaliable rob precious cycles. My personal opinion on these current cards is to stay far away until demand kicks up. The price will fall and the features will rise. Unless of course you require one of these cards now.
If you happen to be in the states, I know getting one of these cards does not guarentee you HDTV or DTV content over the cable wire. That depends on the good graces of your cable company weither or not they encrypt those channels and require a seperate decoder card to view it. Much like the descrambler boxes of olden times.

As far as outside content such as a DVD player that outputs in HD format, you'd have no problem hooking that up. Or even a cable box that has component out, but I would be cautious if you intend on viewing cable on it.
