To be honest, I think a DVD of the seasons might be a bit cost prohibited, even if it was a print-on-demand. then there's the question of quality control, as well as regional (NTSC vs PAL unless they encode it as ALL). Personally, I'd prefer to see it available on iTunes but VHX is good; although they lack S0 still.
With the Movie, short of a sequel later on or some mini episodes/specials, I don't think we'll see a Season 4. I would love it, but that's going to require a lot of funding.
