Andrew,
I'll reiterate the advice you've gotten about nesting the intact BPAV folder
within another folder rather than renaming it or modifying it. This is the key part of the EX workflow.
To avoid confusion and frustration, it should be emphasized that there are two pieces of software that deal with footage from the EX1. The clip browser, which it sounds as if you're using, is just playback software. The XDCAM Transfer app, which everyone is referring to, is the one you want to use. You can find it
here.
Add the folder you put a BPAV folder inside of (adding the BPAV folder itself doesn't work). Now mark your clips and/or subclips and transfer them.
Does anyone know if they fixed the bug whereby clips are duplicated in the FCP browser if you have to software add them vs importing them into FCP yourself? That may determine which you want to do.
Hope that helps,
Zak
