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.
