As stated a few post up, I can't understand why one can't understand "why have two tv's" ? Perhaps where you are you get the option of how supplies are easy in getting a tv with 2 outputs for headphone use. So yes the one tv has one output only (Thats what I don't use) So the second smaller 34cm next to it, is the tv my headphones go in.
So yes, convenient for me. Got it both ways really - I can watch dvd or video or tv just like the people are watching on the main tv. Or which is on a rare occasion, I will watch a different program on the smaller tv which has my headphone hooked in.
