Are DVD versions of TV episodes usually different than the TV broadcast version?
I was watching the ST:TNG series finale "All Good Things" on Netflix the other night. I noticed, there was a difference in the scene where Picard is on the USS Pasteur with Dr. Crusher/Picard as the captain and they are asking/coercing Worf for permission to cross thru.
The difference between the TV episode and the Netflix version is Netflix had extra dialogue (I won't paraphrase/quote the dialogue, unless people want me to :) ).
Why does Netflix and presumably the DVD have this extra footage but the TV broadcast (as far as I can remember) did not? Is this common for all TV shows? I think I read something regarding Friends episodes being SHORTER on Netflix than its tv broadcast counterpart but I'd need to find that article.
