I'm trying to play a rewritable dvd from which I recorded from the freeview which is installed on my recorder but everytime I try and press play I keep getting the code C1300 come up on screen, which means the disc needs cleaing, but I've cleaned it many times and it still doesn't work. Could you please give me some other reasons why it might not work? Is there a way where I can dub the programmes back to the hardrive without reformatting the disc?
