Hi Ray, I'm back. Your TV has only one HDMI input, but it also has a SCART input. If your SKY+ box has HDMI out, you would connect it to the HDMI in of your TV with an HDMI cable.
As for your DVD player, I suspect it has a SCART output as stated above. That being the case, you would simply connect it to the TV's SCART input with a SCART cable. Not sure about where the audio goes on the TV, but there is an audio input, and you probably use that (with the usual red/white stereo audio cables). Unless you connect your audio to a receiver for sound. But you did not mention a receiver.
Edit: I see that there is a second HDMI input on the side of your TV, so if you get a DVD/blu-ray player with HDMI, you could connect it there.
Hope this helps!
