Query: Love the show, but so tired of receiving scratched discs!!

Big Bang Theory, wonderful and funny. Quality of the blu ray however, terrible! I opened it up and put the first disc on, first of all, it was covered in smudges. I wiped clean, and it skipped through out 3 of the episodes. Total bummer. Just such a PAIN to return :(
