I've watched enough TV on DVD to know that you can fit 4 hour-long (45-minute-long) episodes on a disc, so it would take 25, not counting any special features they might add. I know it's not likely, but I'd love to see it. In the mean time I'm also holding out hope that some intrepid individual collects all of them and distributes them in one of the more disreputable areas of the Internet, though I doubt I have the hard drive space.
