In the last year, I've had the misfortune to buy several DVDs that ended up having bad discs, usually manifesting themselves as terrible glitching. It happened again last night when I put on the special features disc to my brand new Star Trek Next Gen movie collection. I suppose now I'll have to take the whole set back and get a replacement.

This has happened so frequently of late that I'm forced to wonder if I just have really bad luck in buying the bad ones that make it through, or if quality control has gone out the window and the DVD-making industry just doesn't care anymore.

However, I have played some discs that have appeared to develop glitching later on on our family DVD player, and they have played fine compared to my personal player. In some cases, I'm certain it's a bad disc. In others, it may be an indication that I need to replace my DVD player.
