Greetings, guys:
I'm considering the purchase of a new, leftover Hitachi RPTV (a CRT unit, the 65S500), which has a DVI input using Version 1.0 copy protection.
I've noticed that Hitachi's newest TVs utilize HDMI inputs, and the copy protection is Version 1.1.
The DVI-equipped TV has superior picture quality compared with their RPTV that uses an HDMI input (the CRT-based 65F710). In case you're wondering, I still prefer CRTs over current microdisplay units (DLP, LCD, etc.).
My questions: Will HDCP Version 1.0 prohibit me from viewing DVDs (via the video digital connection) that Version 1.1 will pass unhindered? How about the upcoming high-definition DVDs? Or DirecTV's upcoming, revamped HD system? My concern is about near-term obsolesence of the DVI digital video connection (the digital audio portion is not a worry).
Finally, does HDMI offer any video-quality advantages compared with DVI?
Thank you in advance for your help!
Alex

  Thank you for the link, Dave. I found it helpful.
  I did some additional research since my initial post. I have been told by DirecTV that their all-new, upcoming HD system is expected to be compatible with DVI-equipped televisions.
  Also, both Hitachi and Pioneer assured me that as long as a television has any form of HDCP, it should be compatible with either DVI or HDMI DVD players (i.e., standard-def players). Hitachi added, though, that compatibility between current HDCP Versions 1.0 and 1.1 and future hi-def DVD players remains unknown, because standards are still unresolved.
  Pioneer stated that as far as absolute high-definition video quality goes, HDMI has theoretical advantages that may or may not be noticeable with typical RPTVs. The rep said the difference likely would be moot with a television that can display up to 1280 x 720 maximum resolution. HDMI thus becomes more important with televisions that can output 1920 x 1080.
  Finally, from looking at info at HDMI.org, it seems that the difference between HDCP Versions 1.0 and 1.1 is that the latter was developed to support DVD-Audio.

      There are a few more differences, but are easily found with a Google search.
