I'm not sure if this will help, but here goes:
My setup: On Digital STB, DVD Player, VCR (2 Scart sockets), TV (2 Scart Sockets) and a playstation.
I have my Digibox going into the auxilliary port of the DVD player with a Scart cable. The DVD out then goes to the VCR in, also with a Scart cable. The VCR out then goes to the TV AV1, with a Scart cable.
My playstation then connects to AV2 of the TV, also with a Scart cable.
My VCR also has 2 RCA composites out to my stereo.
As I say, don't know how helpful this is, but it may just be useful.
