AV Capture from Scientific Atlanta/Cisco 4200DVB

Until my 4200DVB's PSU died, I was able to successfully capture video data from the "VCR" SCART socket (via a ProfiGold SCART-to-RCA/S-video adaptor, switch set to "output") into my Hauppauge HVR-4000 card. Video was output from the adaptor's composite RCA output (yellow), and taken via a composite video lead and the Hauppauge-supplied RCA-to-6-pin(?) S-video lead to the HVR-4000 composite/S-video input. Stereo audio was output on the red/white RCA outputs of the adaptor and input into my mobo's Line In jack via a 2xRCA-to-stereo jack cable.

With the SCART adaptor plugged into the "VCR" SCART scoket, the S-video output only gave luminance (Y) data, resulting in my MythBox only capturing a black and white picture. From memory, using the "TV" SCART socket gave the correct, colour picture. This tallies with reports of SCART "down" sockets (of which the STB's "VCR" socket is an example) rarely implementing the "S-Video C down" function on Pin 7. Unfortunately, as my TV was already connected to the TV SCART output of the STB, this meant that composite video capture was the only option.
