There are a few options that should work, try one of these

Connect the NTL box to the DVDR with scart
Connect the sky box the tv with scart (if the sky box has hdmi use it)
Connect the DVDR to the tv with hdmi

Connect the NTL and Sky box the DVDR using scart
Connect the DVDR to the tv using hdmi

The second option will let you record both NTL and Sky, but i'm not sure if the DVDR will output a "live" channel from both boxes. I suppose it will, give it a go.

When people ask me what I think, I tell them: "I think all of the meat around the pig's ass is pork."
