Usually the cover sheet is shifted up, rather than tilted or otherwise skewed. There isn't much tolerance in height between the sheet and the dvd case insert plastic, doesn't take much to screw it up. But for those cover sheets that are skewed towards the bottom, theft paranoid manufacturers are ready and willing to screw you there, too. Never seems to fail those DVDs that you don't rip the top of the cover sheet off when you pull the seal sticker off are those few with a *bottom* (and, often, side) sticker that rips the bottom of the cover sheet off. The irony is the DVDs that most often get the Fort Knox sticker treatment are those cheap ass budget DVDs that wouldn't be worth risking jail time to shoplift. But the seal sticker games don't end there. For a while it seemed every DVD had these superglue stickers, you know the type - those you actually end up ripping the insert plastic off the DVD case trying to get them off. When you finally do get the sticker off (usually in pieces), it leaves its snail trail of glue residue behind (easy enough to remove I learned, just use the sticker to pull up the residue). Now I say "for a while", because it seemed like they switched to using easier to remove stickers. But I've noticed recently that the glue trap stickers seem to be back. Sometimes I feel I spend more time opening and cleaning off my DVD purchases than I do watching them. Right up there with seal stickers ripping the cover sheet is theft prevention bars sticking right on the inner liner of DVD box sets. You get that multi-disk tv season set, and stuck over the main characters face under the disk tray plastic is that magnetic strip. Not attached to the plastic where you can remove it, not on a separate paper which you can discard (that good idea didn't seem to last long). But attached to the disk set illustration liner itself, so if you do manage to pry up the dvd plastic to get at it and remove it, it will surely rip part of the picture off with it.
