Panasonic DMAR EH75V DVD recorder wont PLAY



Hello all im having trouble with my recorder i posted earlier about recording to DVD-r disks and getting pixely pictures so I thought that I would give it another try and guess what… The blank disk I inserted said “it could not record problem with this disk” So i took it out and let my son watch one of his movies and his movie will not play . It just makes a sound and says ’ NO READ" Does anyone know what happened? Has the blank disk Froze my Recorder?
Ive turned it off and waited 20 minutes and still wont Play any Disks.
