Mine is a Pace box. Connect the bottom scart marked TV scart to Scart 1 on the Techwood tuner box. Are you using a full scart - all the leads wired? Then you will need to choose the input on the tuner box to get Sky.
The scart on the Sky box marked vcr scart connects through your VCR or DVD recorder to one of the other Scart sockets on the tuner box.
