How important is aspect ratio control in a PS DVD deck?? I am about 4 hours from purchasing a new player for my Sony KP57WV600 and need to know if this feature is right for me. I am very particular about how the image fits the screen, but have had really no problem just using the set's different wide modes to fill the screen. For anamorphic DVDs, I have just been using the "zoom" mode on my set which greatly reduces or eliminates the black bars. Also please list some recommended decks that have this feature.

Thanks!
