On the widescreen TV I have, once the DVD machine is set to 16:9 output, the television auto-switches to everything from the player as 16:9. Only 16:9 flagged pictures should be auto-swtiched to, but it does everything! Perhaps the machine is sending out the 16:9 flag itself instead of the information contained on the disks. Am I right in thinking that if you've just watched a 16:9 disk, and then put a 4:3 in (or go from a 16:9 movie to a 4:3 extra), then the TV should switch to 4:3 and then back again if another 16:9 disk is put in? It never auto-switches to 4:3 I have the full auto-swithing enabled on my TV, but it only seems to respond when the EXT1 channel is first tuned into. Once on, it will stay in the same screen format unless I manually change it. Even if I put a 4:3 disk in, the TV auto-switches to 16:9 as soon as I turn over to EXT1. I can't get 4:3 unless I choose it myself via the remote. This is really annoying me!
