Does someone have experience with the differences between composite, s-vid and component cables in a single system? For example, can you tell me what changes you saw, if any when ONLY the cabling was changed? Can a % difference apply here? (component was 50% better...for ex.) I am assembling a system with a HP ep7122 DLP XGA projector and I need to cut some £ from my budget - the easiest way is to wait on a new DVD player. I will instead keep my 1 year old Sony (without prog-scan, only composite video out). My receiver will convert to component. Do you recommend that I run component to the projector as well, or is it not necessary because of the already composite signal?
