I recently got the NASA When We Left Earth DVDs, and I thought “great, I’ll be able to watch them during my Seattle trip”. So, I put them into the hotel DVD player tonight .. and got a “cannot play” error. Arg, the dvd’s will be region 2 (europe) and the player is region 1 (US). So, despite this being a completely legal, paid for copy of the DVDs which I brought with me, I cannot watch them! Grr!
