Here's the thing that's really going to piss you off.
As you know, bitrate, not resolution, is what determines the amount of space every second takes up. So you can increase the resolution and keep the bitrate low, resulting in a less detailed, but smoother image. This is pretty much all that's possible for anything filmed digitally in standard def, as the detail was never extracted when it was filmed. So let's say you're looking at a show like that... something in the 90s most likely. They could fit an entire season, at the original bitrate with upscaled resolution on ONE DISC. But they won't because people see one disc and think "crap." Though it's actually true, in that case, that it would be crap compared to regular blu-rays, detail wise. It's the best possible for that particular piece of content, and if you like that content... you're going to want that.
