If you're freeze-framing single images in an episode and then blowing them up to find errors you won't be disappointed. I bet that 98.75% of the people who watch the BDS would never notice that (or the viewscreen in "Time Squared" clipping over onto the wall.) Hell, do you know how many times I had to watch "Unification II" in order to see the reflection of a stagehand in a set decoration? Or to see the various mike stands and boom-mike dips in the series? And I've never noticed the crumpled piece of carpet/stage equipment Riker was standing on in (Where Silence has Lease?) that was cropped out for the BD.
Stop going through these episodes and scrutinizing them frame-by-frame looking for mistakes!
