Well Jeremy,
I tried to import the BPAV folder and got this error message from FCPX:

It was the same with the CLRP folder. Here’s an image of what’s inside the TAKR folder:

It seems the TAKR has “Mountable Disc Images” in it. It seems like the CLRP folder contains all the video files so I’m not sure about removing it from the file structure, if I’m understanding you correctly.
Ahh! This is such a mess. I’ve also posted in the Grass Valley/Edius forums and will let you know if I get a response there. I think the camera somehow recorded in a Edius specific format and I just have to figure out how to convert it back… which I hope is possible 🙁
