Then talk with your money and drop them. They will come around.
I'll definitely send Netflix an email or something. They don't really have competition, so it's not like I will leave them for somebody else. I have a feeling they will come around sooner or later. They have acknowledged that the future is streaming, not physical DVDs.
I don't know what their bandwidth charges are, but it's probably cheaper than the costs of mailing a DVD both ways, buying the physical plastic discs, warehousing the discs, robots and people to keep all those discs sorted out.
Apple seems to have no interest in an all you can eat plan for music, or video, but that could potentially strike a major blow to Netflix overnight (assuming they had the library and a competitive price).
