Why do you need 240hz tv to play 3d games like ps3, where as dvds can be 3d with any tv? - i want to know about 3d dvds

Games are different, so that the frame rate on DVD
Other films in 3-D over a 3-D seems to be different
Last but not least, the DVD is a constant image, every time I see it is exactly the same, the game is constantly changing, so that a faster processor makes sense - you can play games 3-D penalty of 120 Hz (My TV is 120 Hz and 3-D - tigre invincible playing in 3-D it is very cool), but does not look as sharp as the TV 240Hz
