I've looked everywhere for instructions on how to use the auto switching for 16:9 and 2:35 feature via lens memory. Can someone please post a step by step / menu by menu how to for this? I can't figure it out. Do I put in a 2:35 movie, adjust the screen to get rid of black bars, save, ( but to what and where?) then how does the auto detect work? As you can tell, IM LOST. Step by step like you're talking to a 5 year old. Thanks!!!
