I'm using Redcine X Pro build 14 as well as the most recent, as of 5/17/12, firmware and drivers for the Red Rocket.
I've come across some clips that give a "Error Decoding Frame" when encoding for Avid and spit out the bad frame number. On playback, the Red Rocket seems to hang on these troubled frames.
Oddly, in software-only mode it plays back fine. In both software and Red Rocket mode none of the three affected clips show any signs of black frames, video or audio corruption. As DIT on set, I know these were transferred correctly. It seems like this same issue is being reported on the red user forums, so I'm keeping my eye on the existing thread, but I thought I'd ask here for my own benefit. Maybe it's a firmware/driver hiccup.
As an aside, I ran the majority of the job in software mode as my Red Rocket was being rented to a friend and there were no errors up to this point either. I'll probably just run the clips in software mode (redline, basically) overnight and take a look.
