We did this 7 years ago, and you are absolutely correct. We ended up watching movies rented from Blockbuster, RedBox, ect., and then we noticed something else.

While watching DR movies on Blue Ray, we would notice unusual "things" and sure enough, popping in the 30 year old VhS, bingo. Taken out/added in…..changing history.
