Using LiteOn Ez Dub DH20A4P external burner and Sonic digital media v7 software to burn mp3 audio(not video) files from Inspiron 1300 hard drive to Verbatim DVDRW. Want to store mp3 files on DVDR/RW to free up harddrive space and to playback on laptop. When try to play back, no data found on disk. Any suggestions? Thanks
