      I ordered a Toro, probably the problem goes away if I send the 480p through RGB.

      I’m sorry, but I’m compelled to nitpick here. I think you mean if you send 480p through SCART.

      Your Dreamcast is outputting RGB, whether you’re using a VGA box or cable; the difference is that the default output (with a VGA box or straight cable) is RGBHV, and the Toro lets you select between RGBHV (over the HD15 only, I believe) or RGBS (over both HD15 and SCART).

      I’m not sure if the Toro processes the sync at all when in RGBHV mode (and I assume your existing VGA box simply passes the raw RGBHV through), but its sync combiner (for converting to RGBS) may help work around your sync issues.

        You are right, using the word RGB is wrong in this case.

        But now to my plan: As far as I understand the Toro can send a 31khz RGB(S?) signal through scart. And the OSSC manual says, that you can connect either 15khz or 31khz sources to any input on the OSSC. This would also fit better into my setup, because I can put the Toro into my scart switcher.

          This is correct, and how I have my Dreamcast connected to my OSSC; my Toro is configured for RGBS, and it will send 480p over SCART without issue. (Although I don’t believe SCART devices in the wild will take anything more than 480i.)
