I believe you are both confusing HDMI with HDCP.
HDMI is the digital connector -like DVI. It does both picture and
sound -unlike DVI as you say, which does just picture.
You can buy HDMI and DVI equipment that does not have HDCP.
HDCP is the "copyright protection" system that Sky will be insisting on
(from what I hear) if you want to get that at some stage.
So basically, to be as future-proof as possible, you would need a
HDTV-ready, HDCP-capable screen (tv, front/rear projector).
As long as it has HDCP it _will_ have either hdmi or dvi.
....although my guess is that anyone with that gear will likely sell it
before all of those 'standards' are required. I think anyone buying a plasma
tv in particular at this time needs to examine their priorities. ...Sets
with those specs are uselessly overpriced. Sets without are/ will be
worthless soon.
Sets with will drop in price _dramatically_ once broadcasting standards
become well known/ widely available.
....And by the way... <ahem>... I've been "HD Ready" for over 2 years now
with my Sony HS10 projector. :)
