ok i'll try to explain this the best i can it might get a little long too... my goal is to have a pc attached to my home theatre. the problem i'm having is no matter what how i wire it up i end up frying one of the components. here's how it went: first time: i first hooked up the audio using my sb-audigy into the multisource in on my receiver. that worked. then i proceed to hook the s-video into the s-video in on my tv. as soon as i do that i hear a hum from the speakers and the circuit breaker flips. i ended up trying all the inputs on my tv using the rca out from the pc. well that wasn't such a good idea because now my tv is getting fixed, it has one charred s-video port, and two sets of fryed rca inputs. second time: i still havn't got my tv back but i decided to try a different way of hooking it up with my secondary tv. this time i use the receiver as both the audio and video switching so all the a/v signals go to the receiver then to the tv/speakers. well this time i used optical for the audio and rca for the video, as soon as i got the rca cable near the video card plug i heard a pop in teh receiver and a spark at the end of the wire, it shocked me too (to the point of burning my finger ) so now i have no video switching on my receiver. i really don't care that much about the receiver because it's one of the cheap sony home theatre kits. i've already decided that i need a new receiver so i'm looking at an onkyo tx-sr601. what am i doing wrong here? when i get this new amp i really don't want to end up frying it too. anybody got any suggestions?
