Eeer, not following this thread, and no idea bout all the stuff that is 
going on, but nevertheless:
Avi and Avid? One letter difference, but i never heard that in the same 
sentence...
How are you importing them into Avid?
Do note that Avid makes totally different levels for standard import and AMA 
transcode.
(In my limited tests the latter seems fastest and best)

Or, since you're BBC, do you use WriteAvidMXF?
