It must have been tied in to the time I specifically updated to an older
version of FFmpeg.cpp in order to build - although I was deleting that 
file and updating normally to get a new copy of it, the revision graph
showed I was still getting sent the old 1.8 version. Will have to read
Tortoise help to see if updating to a specific date really then 
over-rides subsequent normal updates, but I quick fixed by pasting in
from the web site. 

I am now getting replicable crashes as soon as I use the FFmpeg importer 
to import anything, and as soon as I try to locate the FFmpeg library
with the Prefs. button. I have saved the call stacks but I'll do a complete
new checkout and re-build first to make sure.
