Sorry - I can't answer your question. I'm new to this stuff myself. However your post interested me because I'm shopping for a t.v. right now and the Philips 30PW9818 is one of the models I'm looking at seriously. How do you think Philips compares with Panasonic for HDTVs? Also, what is this 'Video Essentials' thing you mention? Sounds like a way (a DVD, CD) to calibrate or test a televsion? Thanks.
