My sister just asked me the other day...
"Our DVD player just died. Should we get a Blu-Ray player? Will that still play our DVDs?"
She has a 60" LED TV and using DVDs. Yuck.
Ignorance is abound out there amongst the common population.
I like the idea of being able to download something at higher than streaming quality (legally of course), but to equal the quality of a new movie on Blu-Ray, you would need to download a minimum of 30-35GB per movie with just one audio track and no extra features. Sure, that is HD audio, but isn't that part of the idea.
Maybe start downloading and after enough of it buffers you could start (like streaming does now), but let a gig or so come down before starting instead of 50 MB for current streaming.
Still have internet provider bandwidth caps though.
