Thank you for your insight, Jim.
Call me "silly" if you must. Admittedly, 1) while extracting the audio is a valuable feature, and I've used NXT 2 only a very short time, for my video editing purposes, so far I've found no real advantage.
You see, 2) although I'd love to go to HD, the video Dvd's I create and distribute go to folks who may not have Blueray or AVCHD capability... and many of the LCD projectors at the places where I make the presentations in person are SD units. So, what I got is what I need for now.
I am considering recording in AVCHD my next trip to Africa, then converting it to SD. I'm told that may provide an improvement over recording in SD. I will test it before the next trip, and make a decision based on that. Video editing and DVD production has been a great tool.
Anyway, Jim, thank you so much for your time, your expertise, and your input... and for anyone reading this and looking for information, I do recommend NXT 2.
Time for me to climb back under my rock........
