It's a ground loop problem. run a ground wire from the Chassi of the computer (screw) to the chassi of the device(be SURE it's a ground. I'm betting that your TV does not have a grounded 3 prong power plug on it.
Ground loops are the bane of video/audio equipment and take some time to get rid of. you can get isolation transformers for audio, but no such animal exists for video or svideo

Maybe it's the same problem some people have hearing a deep sound from the receiver when they connect the computer. Do the computer and the tv share the same power line? When two machines are not on the same fuse, this could cause some side-effects like this.
