techsupport@rotel.com was mostly useless, they just suggested i contact the store i purchased it at. I did so, and they (Audio Video Solutions in Laurel, MD), had no suggestions. After poking around on the 'net for awhile, i ran across some reviews claiming that the Rotel 985 is the same unit as the much cheaper JVC XV511 (There are quite a few reviews at that site discussing this, so if you are curious keep reading through the reviews...) Left with not much of an option, i tried dorking around with the Rotel. As it happened, techniques for getting a JVC into test mode worked with my Rotel. Along these lines:
At this point, it was all experimentation. the "5" key seemed to switch the on-screen menus to English. A lot of the menus seemed to be catalogs of icons. I dorked around with it for quite sometime, and eventually seem to have done something that fixed the player. It's playing DVDs again.
I'm fairly sure that it was not just putting the player in test mode. It was something i did while in the menus.
