Re: BD titles that output 1080i/720p w/component video
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.
