Connection troubles...

jducoeurOkay, I'm looking for some ideas here, because I clearly don't understand quite what I'm doing.
We're trying to run some videos from![[livejournal.com profile]](https://www.dreamwidth.org/img/external/lj-userinfo.gif)
msmemory's laptop to the TV system. (Watching Torchwood.) The video side was easy, once we realized that she has an S-Video output, which I could hook into the DVR. But the audio is being a hassle.
The only audio output from the computer is the headphone out. Okay -- I've got several headphone-to-RCA adaptor cables, so I used that to plug it in. Which works -- but it's got a persistent annoying hum, very much like an ungrounded turntable. It's not the cable doing it: I tried several cables, and they all have the same effect. It's not the DVR: plugging the same cables directly into the receiver has the same hum. And I don't *think* it's the computer, since plugging in real headphones doesn't seem to have the same effect. (Although I haven't conclusively ruled out that possibility yet.)
Am I missing something here? Is there something wrong with the idea of using such an adaptor to go from the computer to the A/V equipment? It's not preventing us from watching, but it's a bloody irritant...
