Yes you can, as long as your TV has two SCART sockets. You'll also need three SCART leads (the ones with the rectangular, multi-pinned heads) and an RF cable (with the round heads).

1. Connect a SCART lead from the AV1 socket on the TV to the TV SCART socket on your Sky box.
2. Connect a SCART lead from the VCR SCART socket on your Sky box to the AV1 socket on your video recorder.
3. Connect a SCART lead from the AV2 socket on your TV to the AV1 socket on your DVD player
4. Connect an RF cable from the aerial out socket on the VCR to the aerial in socket on the TV.
