It will usually get width [video][resolution_x] and height [video][resolution_y] fairly reliably.
Playtime [playtime_seconds] is probably accurate if it's a once-through video or animation. A very large portion of Flash files involve looping and or conditional codepaths, so the playtime (if returned at all) is pretty meaningless.
I meant as in the game runtime, - how long is the gameplay.
How long does it take you to play Solitare? or Crysis? it's not a defined time... if it was it wouldn't be a game, it would be a video...
