I only buy brand new DVDs of things I've already seen and know that I love and will want to watch again and again. BUT NOT RIGHT AWAY!
The problem is then I only find out MONTHS after purchasing them that they are defective. Happened to us with Firefly that we got them brand new and at least one of the discs is totally fucked (the one where Kaylee gets her pink froofroo dress!!) with a huge rub-out scratch area.
Then it happened to me AGAIN!! Only the third tv show dvd pack I bought, and on the FINAL EPISODE of Twin Peaks, there is some kind of defect where there are no scratches or visible flaws on the disc, but it keeps skipping, getting green chunks of pixels, and crapping out entirely so you lose your place. Seriously, TWO OUT OF THREE dvd television show collections with defects?
Blarrrrrr! I'm angry!!! It sucks so hard to be watching shows that are like SACRED RELIGIOUS EXPERIENCES/RITUALS and have them RUINED like this!!
