tv-out problem

[illspyder]

Ok i have a radeon 7500 and it does not have s-video out it only has composite out. Now my tv is kind of far away from where my computer sits and i bought a long 40 foot cable from radio shack to use. Now i get picture and everything is ok except that i get this really loud, annoying buzzing sound coming from my tv. I tried just playing the audio without the video cable plugged in and it worked fine, but once i plugged that video cable into my tv again the buzzing came back so im wondering if there is any way i can fix this or if im going to have to buy a new cable or what. help

I would suggest going back to Radio Shack and explain to him what your problem was. he will probably sell you an inexpensive signal amplifier.
