Again, AFAIK, there is no consumer-level HD analog capture solution.  
You can't capture HD over composite or S-Video, and a component video 
capture card would cost > $USD 1000.  So, *theoretically*, yes, an HD 
component video capture solution would get around the encryption issue, 
in the same way that composite/svideo capture currently gets around the 
encryption issue for SD (NTSC) digital cable content.  However, an 
analog HD capture solution would require that your PC (or capture card) 
re-encode the raw analog video frames into a digital form, which would 
require some serious horsepower.  Think about it: it takes a 2-3 GHz P4 
just to *decode* HD content for playback; to *encode* it in real time 
would take quite a bit more than that.  A hardware encoder card that 
would handle HD content would like be several thousand dollars.  It's 
just not likely to be a viable or cost-effective solution any time
