Q: I am a big JVC fan, but I do not like this model, I was suspiscious when I saw several units in the return section of the store. I bought one anyway (new) and must say I am not happy. The unit sends out clicks to the receiver once in a while, the transition between scenes is not always smooth,(like a little pause) and while it is still fairly new I can't get any DVD,CD or even a DVD headcleaner to work. All I get is a "incorrect disc" message.
A:
Negative
