Some time ago there was a little discussion about the BDP-83 sometimes getting stuck in an AR display mode that wasn't correct. I believe it was Bill or Bob who said that just selecting Setup then exiting would often jar the 83 into the correct AR (16:9 Auto mode). This worked. I said I would look for instances where this didn't work. Have to admit I haven't tried very hard since, just done regular viewing and quite a lot of it.
Can the AR be incorrectly recorded on a BD? Or is this a misinterpretation of data by the 83? A recent example is "The Deep" BD (excuse my highbrow viewing, but I was re-investigating the wonders of underwater buoyancy
). The "making of" is identified by the 83 in the info display as 16:9, but it looks correct the way it actually displays as a full-size "regular" 4:3.
Edit: doh, I just realised there's no reason why the original 4:3 feature couldn't have been recorded with the side black bars to make it 16:9, just the way top and bottom black bars are recorded for wide AR DVDs. It's the first time I have seen this with 4:3 on BD though, and I got confused LOL.
