i think one of the reasons that blu ray and hd dvd are struggling is that you really need a big tv to really show the difference between upscaled dvd and hi-def , most hd tv's are c. 32-40" and it's just not big enough !
the problem is - who on earth wants a 60+ inch monster in their house that will look dominate the room and probably look truly awful with sd ?
i think bno are quite correct in being extremely cautious over this whole debacle
for all we know - both formats could ultimately fail and itunes and it's movie service ( soon to be 720p - 1080i hd ) could be the eventual winner
the big advantage of downloads is finding the film and not having your shelves cluttered up with scratchable discs , plus all the hassle of finding the disc tray in the dark etc
i'm all for it as going from a pile of cds to a nice simple to access hard disk has revolutionised my musical activity as i'm sure it has everybody elses
