I'm curious if there has been any resolution to this problem. I'm having the same issue. Everything is hooked up as described in the documentation and the register bits are set correctly (read/written via the system_console). The video still runs but is not locked to the input.

Hi eliljey,
I had not solved my problem. But I don't work further on with frame locking, because it is not the technic which I need. If you want to do frame locking, you have to use the same input and output video frequency. For example, you can't use the 91MHz clock from the video input and use a pll generated 91MHz clock for the output. As far as I know, this both clocks must be exactly the same.
