Nice to see the comparison. Thanks Neil! It appears most of the opticals are still the same. With the exception of the energy beams and the shield that Q puts up are new CGI effects. The shots of planets from space appears to be the same optical, not a new CGI in one shot from Encounter at Farpoint. The darker shots from Sins of the Father will be interesting to see given the better contrast levels that they'll likely have.
Scott, the only issues I've had with blu ray stem from firmware in the player. As newer discs came out, older players might not have the firmware needed to play the discs, so they may on occasion requite updating. I got my player in 2008, a Sony. And so far, I've only updated it once and I've not had any issues. I figure since Sony is one of the companies pushing blu ray so hard on us, their players had better be good! (I just remembered, I have had a hi-cup with one episode of Mad Men on blu ray. But that's it)
I take care of my discs, I never lend them out. So my discs are indestructable from that point of view.

But accidents do happen.
I can understand your reluctance to add blu-ray to your home system. Discs are expensive, but they are coming down fast. Players are getting cheaper all the time. And the cost to replace so many season sets of TV shows is expensive. I only target Star Trek, so I limit my purchases. Plus a few other TV shows. And I am getting copies of favorite movies too on blu ray. And I never sell my DVD copies. I like the fact that I can still play them on my older systems in other rooms. For me, the upgrade to the blu rays of Star Trek TOS are well worth it to me. It feels like I'm almost there on the sound stages at Desilu in 1966. Yes clarity is expected, but color depth is much more amazing to me.
And I'll likely do the same for TNG. The DVDs of TNG look far worse then the DVD's of TOS did.
As an aside, I plan to upgrade to an Oppo blu ray player. Those players are very well regarded for video performance and audio. And can play a greater number of formats. So it will be my hi fidelity CD player and DVD, blu ray and SACD and so on. Of course, you'll need a new pre-amp or receiver to decode the new audio formats. So it never ends.
