Anyone try to use a flash drive to off load footage? I tried using a older 4 GB flash drive, formatted in-camera and only had a single 10 second test clip to transfer. I got a prompt that said "lack of capacity." I then pulled the drive and tried to see it on my Mac and that didn't work, the Mac won't see it. I want to be able to use a 32GB flash drive to off load footage from P2 then transfer it to my Mac for transcoding.
