Video Capture Cards with Component Input/Output

I have just found a Video Capture Card with component Video II/Out. It is called PYRO A/V Link. Can anyone tell me if there are other hardware products like this. It would be great to find a Internal device combined with Digital HDTV.

Also can anyone tell me the following:
1.)Max line or resolution using Pal Composite
2.)Max line or resolution using S-Video
3.)Max line or resolution using Component (YUV or RGB)
4.)Max line or resolution using SD

I userstand that the max for HDTV is 1080 Lines

What is the difference between YUV and RGB?
