Query: Poor quality control in manufacturing

Obviously The Wire is a great show. The 1-star review is for the quality control during the DVD manufacturing. I'm on Season 2, and the DVD freezes up at places and won't play. I tried it on my computer and had the same problems in the exact same places. No visible scratches, and it's the first time I've played the DVD, so it's a manufacturing problem - not something I did. (Others have had this same problem - click on some of the other 1 star reviews to see).Not sure if the cardboard sleeves in the box had anything to do with this, but at this price, I expect better quality control.
