South Park? Family Guy? Why? Animated series made for 480i/p would not look much better in 1080p. DVD quality is fine for standard definition animation.
Off the top of my head, I say...
1. Lost (I've never seen it! I've been waiting for a Season 1 HD set)
2. Dexter (amazing show, piss poor video/sound on the DVD set)
3. 24 (good show, sub par video/sound on the DVD sets)
[quote name='detectiveconan16']You know I wish someone would treat Blu-ray as the media that can hold ALOT more data than DVD, rather than just a high definition disc. That said, if someone bothers with it, a lot of anime tv shows could verily well be on BR. Case Closed has over 490 ep., if Funimation were trying to release more episodes for American consumption, think of how many episodes of DVD-quality can they fit on it.[/QUOTE]
One Piece. Maybe it'll be affordable if they could fit more than 4 episodes per disc =(
But they would end up being about the same price per episode, if not more. Discs and packing are fairly cheap, the big expense is licensing, encoding and distribution. Offering standard definition on BluRay just because it uses fewer discs does nothing but limit their potential buyers -- since far more people can play DVDs than BRDs. To make up for the lower sales, as well as the higher cost of high-definition encoding, their prices would have to increase.
