How about numbering your DVDs with numbers, then throwing dice to decide which to watch... the first number would have to be the number of dice you have... like if you have 3 dice, don't start with 1 or 2, because you'll never land on those... so start 3-18 (18 is the maximum you can have with 3 dice... 6+6+6=18)... then roll the dice, add up the points, and watch the movie corresponding to that number...

yes, an easy, cheap, and non-platform-specific way to handle it...
