I have season one on dvd. I noticed they offer single downloadable episodes on Amazon, but no other seasons have dvd sets. Will this ever happen?

Not sure if it will, but it took quite some time for season one to get onto dvd. As far as I know, the fact that the hiển thị has switched production companies a few times has caused the delay. Pretty much it's all about red tape. Josh has đã đưa ý kiến that they're working on getting the hiển thị to dvd. I guess downloadable episodes are easier to get to market than dvds.
