Indeed. I have had issues with that also. I had a weird case once where when 
using a SCART box to switch between VCR and DVD player outputs one of my TV 
sets gave black and white screen when watching the VCR, but another set 
worked in color in both instances. Go figure.

It all comes from the fact that Svideo has two signals, the luminance and 
chrominance signals. If you miss the chrominance signal (which carries the 
color information) you get B/W picture.  So maybe your adapter cable fscked 
up and wired it the wrong way, or it can be some obscure incompatibility, as 
I experienced.
