The TOS-R Blu-rays are in the OAR in all territories. I imported the US discs, but I would've been fine with the UK releases. I'm confident any future TNG-R BD sets will do the same.
Which I didn't understand since they rendered the effects in widescreen.
I hope they don't stretch or crop TNG for the new series. We watch all kinds of 4x3 material on our widescreen set and we don't have a problem with the bars on the side.
