Success !
I've been playing around with it since lunch finished - i.e. for a while!
The program 'odvr' kept reporting that my test files were an unhandled
quality (the VN-2100PC records in XHQ, HQ, SP or LP).
After some experimentation I found 'odvr' works only in XHQ - not truly
a problem as I never get near the limits of the device storage.
So here we have a very happy bunny now able to do EVERYTHING he needs
using Ubuntu 12.04 Linux.
Thank you all - especially Tim - for exemplary support.
Ain't Linux great!
