ICT may turn out to be an issue in the future, but right now there is no issue from a software perspective.
Personally I think that this is a bogeyman (who of course could turn out to be real). The OP’s question was to what titles could not be viewed in HD via component cables. At this point not a software issue, though I wait to be corrected (at least I’m using component cables and have had not titles that won’t display in HD—nor the suspicion of any that will not). If some come up, then I’ll need to invest in some kind of HDMI switch.
I don't know of any HDMI switches that convert from HDMI to component if that is what you are thinking. There is one that converts analog audio to an HDMI signal, but I haven't seen any that go the other way.
The HD Fury converts from HDMI/DVI(HDCP) to RGB, if you can use that. Or you could use an RGB-to-component converter after the HD Fury. May cost a few hundred $, but could be better than buying a new TV for some. Many good comments on these in the forums.
Neither do I Doug. I wrote unclearly as my problem is that my display has only one HDMI input (already being used) so I’d need to get a new AVR with multiple HDMI inputs or just a switch that would accept several HDMI inputs.
But I would imagine that by the time ICT is implemented (if ever) the problem will be moot.
