Just found out that I can still get a synched black/white picture on Y in the
CVBS+Y/C mode, so if C cooperates SVHS should still work. Even found an
somewhat hidden SVHS connector on my .... old Philips tv. Maybe some sort of
protection circuit would be advisable to prevent that nasty current leak. Any
ideas?

If your Y/C still works like mine supposedly does, it should be possible to
convert that into CVBS using an resistor network. Don't know how, just read it
somewhere.
