Here's how the Samsung BD player apparently works - they have a function called BD-wise, which automatically inputs the resolution of the DVD itself to the TV - so if it's standard DVD that's what it outputs (if I'm reading correctly).  If you turn off BD-wise, then you can choose how to upconvert, but I have no idea if I'm interpreting any of this correctly.  Interestingly, the new amplifiers they sell also upconvert from standard DVD players - so that must work fine, yes?  All my stuff is seven years old, and I think we all know how antiquated electronic gear gets in seven years.  Only speakers seem to survive the onslaught of changes.
