HDMI, COMPONENT or SCART

hello, if your dvd player is'nt a hd dvd player it'nt not able to be converted into a hd you'll have to buy a hd dvd player,and for your sky plus you'll have to call your program supplier for the hd box,and yes the 4500 is the same as the 4710 its the same t.v. all even newer t.v.'s still offer the "s" video option for people who still want to use a old vcr with there newer t.v. for example thay can still use "s" video.
