While I was building my HT, I came across two 6 ft Monster Video 2 composite cable's, and 2 6 ft Monster Interlink 250 audio interconnects (each cable having two actual cables conded for L/R audio). If I put these two cables together using couplers from rat shack, I can make a cable long enough for my component video run. I would use the video cable for Y and the audio interconnect for Pb/Pr. Is this a good idea? I know it works because I have it hooked up right now, but I'd like to know if this will affect the quality of the signal. Right now I am running my interlaced DVD player through them, but I do plan on upgrading to progressive scan soon and may even run a 1080i/720p signal through it. Thanks!
