I'm thinking of getting a new DVD player. Was looking at the new top of the range Sonys. What are the main differences between the 705 and the 905. The one thing that will make me get the 905 was to have 2 scart sockets as the 705 only has 1 (Running Sky with RGB pass-thru) But it seems pointless to spend over £100 just for that! Any comments would be grateful! Cheers.
