RE: yesterday's copyright issues and copying...I often will make what are considered back-up copies of DVDs which I have been known to share with others...however, I would not ever copy a legit release for resale.
As for grey market items...well, I have no problem purchasing grey market DVDrs of movies and vintage tv shows that companies like Universal, etc. can't seem to feel the need to release...some of these studios have a plethora of classic and not so classic films from the 30s, 40s, and 50s sitting in dusty warehouses...and by gosh I want to see these movies! So when collectors who have transferred their 16 mmm collections or old to DVD want to offer them up for sale...well, I am all over that! And I feel no guilt. And if Universal should ever decide it is time to release some of their more obscure B movies...well, I will be the first in line to buy their product!
