I noticed new footage in The High Ground. The terrorist leader has a bit longer discussion with his subordinate who was detained, about Riker's desire to negotiate for Crusher's release.
Also I noticed in BoBW a warp flyby of the D that appears CG. It sticks out because it has some unique motion blur.
And I too never noticed the early S3 uniform's horizontal seams until now.
Watching these shows in HD is thrilling.
