I've been trying to burn out my MP3s on a DVD to play on my 2007 REL Radio. But whenever I insert the DVD it says "Disk read error". I've tried searching the forum and seen suggestions to try different media. I've tried Sony, TDK and Imation with all the same result. I use Nero Express to burn a Data DVD and making sure it's not a multisession disc. I even tried with 240 MP3s on a DVD and it didn't help. Would appreciate any suggestions, thanks!
