Best Buy eh? They can suck it, they were selling Monster Component cables for Xbox, and they are charging 60 bucks. The salesman recommended those to me. Yeah, that's going to happen. I bought standard Xbox component cables, those work great.
But on a side note, for video/audio, dont buy REALLY shitty cables unless you're desperate and broke. My friend had these cheap transparent green (trying to match the controller cords) 3rd party component cables for Xbox, and they were so poorly shielded it was SICK. I don't necessarily mean outside interference, either. Let me give an example, if you get a lot of bright, intense colors on the screen, the sound would get distorted and your speakers would be buzzing angrily. Alternatively, if you had lots of sound going on it'd cause problems with the picture. I made him chuck it and buy the standard component cables. Live and learn, right?
