Wasn't sure which thread to post this in but, since it relates to my DVD player... Why is it that some devices will force a television into widescreen mode when outputting an anamorphic 16:9 picture, when others do not? I have a Philips 28" Matchline Widescreen TV and a Panasonic TH-37PV500B Plasma screen and have observed the following: Does autodetect aspect ratio: Xbox 360 (PAL-50,480i, 480p,720i,720p,1080i/YPbPr) Amstrad Sky Digital Receiver (RGB SCART) Does not autodetect aspect ratio: Xbox 360 (PAL-60/YPbPr) Cambridge Audio DVD77 (480i,480p/YPbPr) Archos AV5100 (Composite SCART) Nintendo Gamecube (RGB SCART) What's odd is that my DVD Player does not switch the TV into widescreen on either TV, despite having 16:9 mode set in its options. What's even odder is that the Xbox 360 will switch the TV to 16:9 mode in every setting except PAL-60. And what's odder still is that my original Xbox (now sold on) would sometimes switch and sometimes fail to switch (and that's just the dashboard). How does this process work (or notwork)?
