Hi my name is Chris and I am writing to ask some questions about my dvd recorder.I have a dvd recorder rewriter and I have a camera that I have recorded things on I have purchased some blank dvd-r disc from Walmart and I hooked my camera to the dvd recorder and it recorded the things in my camera but when I put the recorded dvd in my other dvd player it does not play anything it says disc error please eject disc and in my dvd recorder it plays just right.One person told me that I might have to purchase the dvd-rw disc and the another person told me that there are other steps to take besides just recording on the disc so if you would could you please give me some information about this and a contact number that I can call if I need any more hepl because the number that is on the top of my recoder is not a valid number anymore. Thank You
