I have'nt used my Dvd Recorder in a while, and I tried to use a couple of days ago and it does'nt seem to work right . Everytime I put in a dvd disc, it's showing a " No Disc" message when there is a disc. I tried all the troubleshooting I found in the manula and even bought a dvd disc cleaner hoping that it is just dirty & need a little cleaning but still nothing. Please help!
