Sync stripper has arrived and just as predicted it has fixed my problems up, well mostly haha
Saturn, SNES, Genesis, and my Supergun all look magnificent on it.
My Analogue Interactive CMVS unfortunatly has a bit of a darker picture, not bad though just wish it was a tad bit brighter. Talked to Christoph about it and we deduced it was the 75 Ohm resistors he built into the video encoder so I just have to max the brightness on my monitor and live with it.
My RGB modded N64 has absolutely no picture at all and I don't know why, works just fine with my XRGB mini
and my Dreamcast has a scrambled picture, so no TATE dreamcast shmups I'm afraid
I'm getting my PCE modded for RGB so hopefully that works with it but so far its looking pretty damn awesome.
I tried posting a pic but seems photobucket is down for maintenance so I'll do it later
