Considering how many unseeded episodes are floating around out there, good luck.

This. When all else fails, and this is the only way, then it is the way. I, too, am more than happy to pay $ for a high quality physical media, but if they aren't satisfied with my one time purchase, and instead choose to force me to pay for each subsequent rewatch if that is what I desire, then they will no longer get my business, and I'll find other ways to get what I want. Why should I not?
