Just got Comcast to put in the HDTV box and I wanted to confirm my settings. My TV is 16:9 It is set for 16:9 YPbPr is set for 1080i, for some reason 720p doesnt work. 4:3 Override is OFF Are those settings correct. The picture on both non HD and HD are great, so I'm assuming everything is cool. Here is my problem: Before getting the HD box, I had PIP and POP. Now there is a message at the bottom of the screen saying PIP does not work with INP-DTV. Is that right? I can't use any of my PIP/POP features of the television in DTV mode?
