Thanks borate for the tip - I'll keep it up my sleeve in case anything goes wrong with what I've tried since my first comment (I use a 64-bit version of Windows 7, BTW). What I did was drag-drop my media into Media Bin, then EXPORT VIDEO | EXPORT WIZARD | FILE | 3D VIDEO FILE . Again, it required a manual entry of Export File Settings for each file (usually just the file title) but they all appear in the Export Queue panel with those waiting for processing shown as "Pending...", and I can disappear off to bed. Many roads lead to Rome it seems. I guess the developers left earlier versions of the various subroutines in-situ as they went along in order to keep existing users happy after the various updates. Most of us users are creatures of habit.
