To preface this: You should check out www.avsforum.com. They are one
of the best audio/video sites on the Internet and I am assured by my
coworkers interested in MythTV that they have some really good
threads on Linux integration with HD content. Anytime I'm looking for
information on Home Theatre/High Definition or other related
technologies it is one of the first places I visit. You can probably
pickup a ton of information there.

To answer a few of the bullets:
-Yes, you can capture true HD content if by "True" HD you mean 720p,
1080i, etc. since most (all?) HD broadcast stations have chosen one
of the two as their broadcast format.

-On some GCI Cable boxes, which may defeat the purpose of this thread
- the Pace DVR silver box with blue display or the Motorola DVR boxes
there is a firewire port, which you can record the video streams off
of. It is a digital feed and although I haven't seen it record HD I'm
told it is capable.

Otherwise you can go for a Component video + digital audio solution
to dodge the DRM from any high def (but not necessarily DVR) cable
box. I'm assuming at this time that there isn't a method to get HDCP
support in Linux DVR applications. On the GCI DVR's (I don't know if
this is the case with the non-DVR boxes) if you turn off the cable
box then hit the "Menu" or in some cases "Settings" a menu will pop
up allowing you to change the output video resolutions outputted by
the box.
If you are interested in using the Firewire port do some searching on
Motorola 6412 Firewire recording. It is probably one of the better
bets to avoid having to acquire a ton of new hardware or interface
cards yet be able to get good quality video off the box. Just to re-
state, the firewire port is on the DVR boxes so it maybe self-
defeating to discuss building a DVR using firewire as the source if
you already have a DVR :^). I have no experience with the non-DVR
boxes so I'm not sure what their port array is.

-I don't know about HDCP hardware on Linux, last I knew the only
official OS to support HDCP/HDMI so far is Vista.
