hi. im a bit confused. i was in a store buying a HD cable receiver, and of course the thing doesn't come with the hdmi/dvi cable. during the sales pitch for the cable, he compared rocketfish and monster cables. in my experience, it's just a name brand, either is just as good the only difference is money. but he said something that made me curious. i was on my lunch so i couldn't get into further discussion with him but here's my question. he said the big difference b/w rocket and monster was the shielding. monster has better shielding. apperantly with rocketfish, if you have a lot of electronics around your setup, it can cause interference. this piqued my curiosity because i am having the exact same problem with my rocketfish Optical audio cable. after an hour or so, the sound starts crackling and there's noise. im an electronics technician, so i know that electronic noise shouldn't interfere with an optical signal. as far as i know anyway. so is this a fact? or just sales BS? i just want to make sure. i have a Belkin HDMI cable running from my dvd player to my tv, and i haven't had any trouble with that at all. do you think i should try a monster cable optical audio cable and will that solve my audio noise? ANY help is really appreciated. thanks a lot.
