Jvc Dvd Vcr Combos Bad Product, No Tuner Does Anyone Have Any Suggestions On JVC DVD Players?

Does anyone have any suggestions on JVC DVD players? - jvc dvd vcr combos bad product, no tuner

I have two DVD players from JVC. One of them is a 3-disc changer, the other is a combo DVD recorder (only 6 months). Both are distorting the picture and freeze all the time. I tried cleaning the head with a hard disk from JVC.
