I have an audio hum w/ my new DVDR...
I bought a Samsung DVDR 2 weeks ago & when I turn it on,I hear a loud humming sound.I only hear the hum when I turn on my HT items to watch TV but,when I watch a DVD-R or a DVD movie I do not hear the humming sound.The Optical cable is also 2 weeks old.If I bought & installed a Dayton Isolation Transformer will or should that get rid of the humming sound.I do not have any cables that are touching or laying on each other.The cables are the Acoustic Research brand.Inc. the F type cables leading to the TV & coming out of the wall to the DVDR.The (5) 16 awg speaker wire is also made by AR.Everything that is HT audio wire ( to & from speakers) has banana plugs on them.That humming sound is driving me crazy! Thanks for your time!

You will probably notice that the hum is gone. There are two ways to solve this problem. You can connect a ground loop isolator at the cable wire. If you have a cable box connect a product like this one I use just before the cable into the box. It has a male and a female connector so just connect your cable wire to the female end and the male portion to your box.

If you don't have a box simply connect it before the cable connects to your TVs coax/cable input. That should cut this crap off at the source.
Another way to fight off this hum without having to disconnect your cable wire is to get RCA ground loop isolators. I went the cheap route and got 4 of them from Radioshack for only 16.99. Luckily they had them at the store so I could test them and return if I did not like them. I like them and they do the job admirably. I use both type for my 7.1 setup with multiple separate amps. No hum at all will ever be heard again. It is well worth the $130 total to be sure you have all sources of ground loops eliminated.

It sounds like you really need to cut the ground loop at the cable wire.
Good luck.
