Dug up a couple other pieces of info: SCART may not support S-Video out if it's wired for RGB:
"Both S-Video and audio (mono or stereo) signals can be transferred through SCART connections as well. However, it is not part of the original SCART standard, so many SCART-compatible devices do not support it for this reason. Also, S-Video and RGB are mutually exclusive through SCART, due to S-Video using some of the pins allocated for RGB.
Most SCART-equipped televisions and VCRs (and almost all of the older ones)
do not support S-Video, resulting in a monochrome picture if such a connection is attempted, as only the luminance signal portion is usable. A monochrome picture could also be a sign of incompatible colour encoding: for example, NTSC material viewed through a PAL-only device."

SCART connectors
may output RGB as well (depending on your equipment) and if they do, I don't believe it's compatible with Blackmagic Design products, most of them accepting only YUV (YPbPr) signal:
