Ghosting on SKY DIGITAL after adding dvd recorder.

Hi All
I have just bought a LITEON 5026, set up was no problem and i have good picture on ordinary tv channels, however on SKY Digital i have some ghosting, although not serious it is a bit annoying. I do not have component connectors on my tv just scart, i have connected the liteon as if it was a video ie scart from video output on sky box to input on liteon and from tv output to the tv, i have the tv ariel coming into the back of the sky and from there to the liteon and then into the tv socket. Sorry if this is a bit confusing! also could interference cause ghosting by having the sky box to close to the recorder, or is there a setting i should be changing on the sky box??
Any help greatly appreciated
