Thanks, but I can’t take it on account of me being English… 
Yes, I’ve heard quite a few stories about X. Thankfully the last time I had to put up with working on FCP was version 7, and I found even that a pain to work with, especially converting the sample frequencies of the clips.
And I agree with you that Nuendo should have a simple option of converting sample frequencies upon importing an AAF whilst retaining the edits.
Nonetheless, your editors should be aware that there are standards in the broadcast sector, one of them being that audio material is processed, exchanged and broadcast with 48, not 44.1 kHz, ever. Submitting anything else in an AAF is demanding special treatment, in my opinion.
