@MrZammler:
If I understand it correctly, you can set the refreshrate of the PicassoIV flickerfixers output freely. To make it synchronise with say PALs 50Hz refreshrate, you would need to set the refreshrate of the PicassoIV flickerfixer to an even multiple of PALs refreshrate which would be either 50Hz or 100Hz. With NTSC that would be 60Hz or 120Hz.
