I was using 2-16GB SXS Pro cards from Sony and the camera and cards are mine, not rentals.
Recorded at 1080 60i (SQ). I had recently deleted one card using the camera and the other card was new.
That being said, I did resolve my issue. I had changed some of my BPAV folders names because I had so many – BPAV-1, BPAV-2 etc… When I renamed them back to BPAV the transfer software recognized the clips and I was able to import without issue. I also did download the new transfer software, 2.7. Which may or may not have helped.
In any event, I will chalk this up to User Error, again! Thanks for you assistance.
