Do you have the OSSC set to Optimized mode? That can make the picture fuzzy if you don’t tweak the timings. If so set it to Generic mode.

The remaining sync issue could be caused by the RGB cable. Do you get stable sync when you connect the yellow composite cable to the green input of AV2? You should see a black&white noisy picture.
