I think it might be possible that one of those scart sockets will have a video/audio out signal as well as an input - scarts are bidirectional.
You wuld need a scart plug to composite/audio OUT lead lead to test it. Sometimes the menu options will allow you to choose what is fed to the output, so have a browse through them.
The idea would be to feed your console to the TV, and record on the PVT via the scart output.
