I think it's a TV issue.  My panasonic TV has three SCART input
sockets: two offer composite or S-Video, one only offers composite. 
As I cycle through the AV inputs I can select.  AV1, AV1S, AV2, AV3,
AV3S ->  .

Selecting AV1 when the AV1 input is S-Video gives a black and white
picture and vice versa.

If I'm sending an S-Video signal, I need to select AV1S.

Hope this helps.
