I want to use headphones to listen to my Panasonic Viera TV, which only has a digital optical out on the back. I have read that using a digital to analog audio converter (DAC), along with a TOSLINK cable, will not work on digital cable channels such as the ones provided by Comcast. I also have a Samsung TV with a headphone jack on the side and digital channels come through the headphones just fine. Since the headphones are analog, does that mean there is a converter built into the Samsung TV or that the digital signal is being converted in the cable box?

Also, is there a way to use two sets of headphones with a DAC? Any help would be much appreciated.

Using a DAC should work fine as long as you get one that supports Dolby Digital (most of the cheap ones do not).

Your Samsung TV has a Dolby Digital decoder built into it (, so it uses that and then outputs the sound as 2 channel analog through it's headphone jack, that is why it works fine.
