60, 24, and 120??
Thanks-a-ton for your suggestions and the useful links.
You were right. I managed to activate 1080p on the samsung bd upconverter. I noticed that when I played SD discs 60zh was on and when I played BD discs (i.e., Planet Earth) 24hz was on, the info screen. I'm assuming this is the way things should play. Not sure if 120hz should show, since our new samsung lcd a650 has 120hz??
