I don't quite understand this either/or "let's focus on the big thing" approach. I think most everybody agrees that the streaming business is growing much quicker and is the future. But as others have noted, the businesses are not independent from a user perspective, they form a synergy.
For example, when Motorola split into mobile/home and public safety/enterprise divisions, this made quite a bit of sense (and they were desperate anyway) because there was little overlap between those. To a lesser extent you can understand HPs spinning off the PC business to focus on printers, but in this case, although the underlying delivery mechanisms and business cases are very different both are DVDs!
Think of companies going the other way, consolidating information to create user synergy, i.e. Google adding tweets to search results.
