My dvd won't play. every dvd i put in, it says bad disc. the vcr works fine. is it time for a new system. i tried a head cleaner and it says bad disc

Hello,
Not necessarily time for a new one. I would give the DVD player a good cleaning before you consider a new unit. A good cleaning disk with some little bristles on it. Run it through three full times. DVD players are far more sensitive than VCRs and have to be cleaned even two weeks or so. When they get real dirty it can take some fooling with to get the DVD player to even accept the cleaning disk. But if it just won't accept the cleaning disk and you can't watch a DVD in it then it's time for a new one. I had a DVD player one time that took an hour of fooling around with before it got cleaned good enough to play DVDs. Worked for a couple years afterward.
Regards, Tony
