hey guys, i just got my panasonic 42 inch plasma screen hooked up today and i was was wondering if its ok to listen to music on the dvd player while the screen is blank blue? will this leave the dreaded 'after-image'? i usually listen to music for long periods of time and today i listened for about 20 minutes switching back and forth from tv to dvd player. the reason why i even play music on the plasma screen is because it has the best sound system in the house, and i like to crank it up ... if it truly is distructive then is there a way to combine both inputs so that i can watch tv on the display and the listen to the music on the speakers, or something? thanks guys... and also, since this is my first plasma tv and since i paid a pretty penny for it, what are the do's and dont's of the plasma screen?
