Hi all! I am hoping someone here can help me. I have a cyberhome dvd recorder ( model dvr 1200 mu ). Each time I try to use a sony dvd+r disk in it..... I get an error message saying that it isn't a supported media type. I have tried several different dvds in it from various cases. So I know all the disks can't be bad. Has anyone had this happen? Did sony change their dvd+r disks? The blank dvds are just the standard type of dvd+r disks. They are not double sides or dual layer or anything. I am really at a loss at what to do. Can anyone help? I tried calling their support number, but they said their phone support is no longer being offered.
