Hey Craig,
I have no problems with SxS. I have FCP version 6.06. I use ShotPut Pro to back up the BPAVs straight from the cards and 60 GB hard disk to two external drives (I use ShotPut instead of Clip Browser).
I then import to FCP using XDCam Transfer from inside FCP (are you saying this is bad practice?).
Not all the clips on the 60GB hard disk showed the NO CODEC error – only the first few, which I recorded on Day 1 – the rest that I recorded subsequently were fine.
THx in advance,
Heinrich Dahms
