Thanks, Roy, for the detailed response. I'm going to continue experimenting, and I'm sure that your tips will help.
One other update. Based on some earlier posts in this thread, I investigated HD media players, and decided to experiment with one from Seagate. The unit uses one of Seagate's small external hard drives, which I already owned, so the investment wasn't too significant. It has an HDMI outplut, so I can produce a move to a file, copy it to my hard drive, dock it with the player, and just hit play.
So far, I'm pretty impressed. It takes some time to figure out how to configure both the video editing software and the player, but my last test (using PD) was excellent. Similar experiments with Studio were not very impressive, but I'm still testing the settings.
I'm going to experiment with some of the output settings in PD, as discussed by Roy and others, but if anyone has any tips on what to use in this situation, please feel free to let me know. At this point, I'm basically using the best resolution available, since the only impact is hard drive space, which is cheap these days.
