Query: Great movie, bad DVD

The movie itself is well worth seeing. Very entertaining and pretty historically accurate, but...I bought the DVD at Best Buy and it "froze" early into the movie. I exchanged it at Best Buy for another DVD copy and that one froze in almost the same exact spot! Luckily I got my money back.I'm not going to bother trying another copy. I don't know if Best Buy just got a bad batch or if this glitch occurs in most of the DVD copies.
