Anybody know if it's harmful to a DVD Player if you never (or rarely) utilize the "STOP" button? That is, in lieu of hitting "STOP", you hit "OPEN/CLOSE" each time you want to stop & eject a disc? Will some built-up damage to the laser within occur if you go straight from PLAY to EJECT? I also tend to never use the POWER button to turn on the player (since hitting "OPEN/CLOSE" activates the power on my unit). Are all (or nearly all) players like this, with OPEN serving as an auxiliary ON button? Thanks.
