I mean, the dvd player doesnt create any heat because i never have it on, but once i turn my ps3 on it gets a bit heated, it will heat the dvd player on the bottom and im not sure if thats bad, is it heating the ps3 more this way?

also, i sometimes take the ps3 out and place it on a low table i have to play, is that a better idea? Or is moving the ps3 constantly bad for the system. I m not sure if its only bad to move it while its on or not
