im looking to buy a new dvd player..however, i dont know if there is any point buying one that upscales. my plasma has 3 scarts plus a component input which i want to make use of. in the manual it says my tv has scanning formats of 720p and 1080i. will i benefit from a player that upscales connected via a component cable or should i just stick to a scart lead. also,my sony strva555es receiver has component in and out sockets,whats the reason for this when i can go straight from the dvd player to the tv? hope someone can help!
