S-Video on G400 secondary output??

[TonyC]

I was about to connect the S-Video output
of my G400 secondary output to my TV's
S-Video input when I realized that the
connector is very different... Are there
different S-Video connectors out there? The
G400 dongle has two cables, one is RCA, and
the other is labelled 'S-VIDEO', but it looks
like no other S-Video connector i've seen.
It's got more than 4 pins and is keyed very
differently. Did I buy the wrong cable?

Help!
Thanks, Tony
