Mystery Buzz between DVD player and CD Burner

[Teasing the Korean]

I have a freestanding CD burner hooked up to my stereo, which I use to burn vinyl onto CD via analog RCA inputs.

In another room, I have a DVD player, with analog RCA audio outputs that hook up to my TV.

I was attempting, for the first time, to burn audio from a DVD onto a CD. I lugged my CD burner out to where the DVD player was, used the same RCA cables that went into the TV, and plugged them into the analog inputs on the CD burner. When I previewed the sound in record mode, there was a substantial buzz that was nearly as loud as the audio signal on the DVD. I was using the very same cord I’d used to plug into the TV, so I doubt a faulty cord was the issue.

I’ve grounded turntables, of course, but never had to ground any other audio equipment. Is this likely the issue? If not, where might the buzz be coming from? It seems like a pretty straightforward setup. Any suggestions?

do you have your set up connected to tv-cable/antenna? If so, your coax is likely "leaking", there are cheap and simple gadgets that filter out unwanted frequencies from the antenna signal. Can't provide you with the english term for these though.

The filter Couw mentions is called "ground breaker" in english

They can be found for less than $15.

If you only do DVD-->CD transfers occasionally, just unplug the antenna during the recording.

Thanks all! I'll try these suggestions!

It didn't work. I unplugged the antenna from the TV; unplugged the video from the DVD; turned off the tv; turned off the overhead light. The only things on were the DVD player and CD burner, with the cable going from the audio out to audio in jacks.

What gives???
