>> For some reason, everything appears black-and-white on my TV, no
color at all

Does your TV do something daft with S-Video input like mine.

AV2 input on my TV is Audio L+R plus Composite Video plus S-Video.

It selects between Composite and S-Video using AV2 and AV2-S (and to
save on electronics the "Y" element of the "Y-C" SVideo and Composite
input share the same circuit). Also the SCART socket definition does
this too, whereby the "C" element is actually on the RED-IN, thus unless
you TV auto detects, or is otherwise told, you get Black and White).

On my TV if I select AV2 instead of AV2-S it only uses the "Y" element
of the "Y-C" S-Video cable and consequently shows and black and white.

My Dad had the same problem with a camcorder as the source, but some
menu option on the TV sorted that out. 

Hope it helps
