Can one use RCA cables (red/white/yellow) in component jacks (red/blue/green)? I understand that the jacks carry much different data/signal/whatever, but I was told that there is no need to buy (very) pricey component cables...you can actually just hook up good quality red/white/yellow RCA cables to the component jacks for the same purpose.
My backstory: for some reason, I am a complete AV dolt. I don't get it and can't wrap my head around wiring and hooking up my new digital video box, home entertainment receiver, and new LCD tv with all sorts of in/outputs.
So, I went to radioshack (ugh...hate that place, but I was in need of a quick fix to get this all hooked up) and the guy asked if I had component outputs, and that hooking these up with component wires (the three red/blue/green wires) would give me the best possible picture. So I bought some $45 package of Monster component cables (knowing full well that this guy was probably upselling me and raking me over the coals...but not understanding enough to be able to know for sure...hate that feeling).
I got home and my friend who was helping me set everything up mentioned to me that it was merely the inputs that were different; the component jacks were what carried "better" picture data...the cables (within reason) were more or less irrellevant. The cables just carry that signal.
I tested it out...and over the short distance hooked up (about 2'), I noticed no change in picture quality whether the component jacks were connected by dedicated (expensive) component cables or by good quality (but 1/2 or more as pricey) RCA cables.
I found this discussion on Yahoo Answers
...but it seems like there if just a lot of back and forth ("yes, they are the same" and "no, they are totally different.").
Should I return these expensive cables and just go with some high quality RCAs in the component jacks? Are dedicated component cables really only marketed for suckers like me?
