Yeah you are right. My ratio is correct now. Does yours pass Dolby digital? My boxes from 15 years ago pass dd.The aspect ratio settings on this thing seem a little flaky to me. And as usual, the box doesn't remember the aspect ratio setting you chose for each channel, requiring you to reset it each time you change channels. (Why is it that only Zenith/Insignia was ever able to get that right? Maybe they took out a patent on it )
To change the aspect ratio, push the button right under the red button at the top of the remote.
