I do have a few questions, that I hope the more experienced users of this set, can help me with. Sound 1. What is the difference between "base" and "3d base"? 2. I have my digital box connected to AV1. However, I am not sure I am getting a stereo signal, since it doesn't post anything about sound, if I press the status button. Is there any way I can make sure that I am receiving a stereo signal? Picture 3. What are the best settings for "sharpness" and "p-nr"? 4. Regarding pal progressive; Is there a difference in the picture quality-vise, between using the tv's internal progressive function or feeding the tv a progressive signal from a dvd player? Does it flicker as much? Im asking this, because my dvd player (denon 2800 mk I) only supports NTSC progressive; in other words, would it be worth upgrading to a player with pal progressive? Thanks in advance for your help!
