I am so sick of this: I buy something and I start enjoying it, and then the picture goes all pixillated and digitized, and skips around with intermittent sound!
It just happened to me with Lock Up and I ordered that from Amazon as it's not easy to find in stores any more.
But I've also hated it with box sets like Star Trek: Enterprise and Miami Vice - where I refuse to return a whole box set, just demand they break open a new set and give me an undamaged replacement disk.
But the effort really bugs me - especially when they can record the darn DVDs for pennies and usually charge around $14 for each movie. Grrrrr.
I'd expect some quality! You didn't have these problems in the good old days of VCR tapes.
