Using Grex with Blu-ray Player

I have a grex digital video stablizer that I’ve used in the past with my old sony dvd player. I recently bought a Sony Blu-ray player (BDP-S350). I am playing a regular DVD movie and trying to record a copy with my Sony RDX-V555 recorder (using the grex). I get audio but not video. I’ve tried several different wiring options and nothing works. Does anybody know if you can use the grex with a blu-ray player?
