Regardless of media, business structure, delivery mechanism, company name, etc. methinks what all customers want is a single place to choose & queue content, filtered by whatever options they desire, delivered on whatever medium is available and they pay for via a spectrum of contracts (from unlimited-per-month to single order).
Just make sure it's all on one queue. If multi-queue, then only because one customer may be grouping for multiple individuals (ex.: husband wants ultraviolent scifi, wife wants sappy romances, kids want Elmo galore). Whatever you do, don't force the customer to spend time/effort along such artificial differences as media (ex.: I want the DVD of "Scarface", but it's not on streaming anymore and I don't want to pay extra for the BD version - let me pick those options based on my single content choice, don't make me search 2-3 different sites for the same title which, I notice, have unreliable availability).
Amazon faces the same issue: vast business differences between warehouses of books & other physical stuff shipped by mail, vs. server farms for Kindle, streaming video, cloud storage/processing, etc. - same problem as Netflix, yet they're doing well under one website. I can search for Moby's latest album, and when ready to order can with ease choose between CD, MP3, DVD, and instant video: same content pool, same checkout, easy delivery, user doesn't care how it all happened.
