I'm in the middle of watching my new blur rays of TOS, and I notice that the DS9 episode of Trials and Tribble-ations is included, in HD, as a bonus feature on season 2. So has that episode been remastered for blu ray then? Since it's on a blu ray disc you'd think so, but I'm not 100% sure on that. It'll be neat to see at least one ep of DS9 in blu ray quality at least. I'll either be watching that ep tonight or tomorrow as a "double feature" with TOS original Tribble ep.
It's a fun ep, I love seeing the DS9 crew in TOS era costumes, Dax in particular is a lot of fun in that one with her excited to be back in the 23rd century, and learning of her past life encounter with McCoy.
