I recently bought a Sony KP-57WS510 CRT RPTV. It has a feature called "Auto Wide" that selects the aspect ratio automatically based on the input signal (at least with DVDs). I was able to see this feature in action when watching a DVD once, but at one point I was forced to override the aspect ratio setting manually, which apparently disables Auto Wide for subsequent viewing. I couldn't figure out the way to get it back, though. Auto Wide is not one of the explicit choices among the "Wide" settings. The manual unsurprisingly also has no explanation about this feature, save for a passing mention in the list of features in the very beginning. I wasn't able to see Auto Wide work again, even with the DVD where I had first witnessed it in action. Does anybody now how to re-enter this "Auto Wide" mode on Sonys? What's the trick for getting it back?
