am new so bear with me. dont know how to reach responders so can use help. I have sony 510a. Copies but will not show on computer or dvd player under simple backup. Will show on computer only under advanced backup. Have spoken up to Tier 2 tech support and they were bumping me to tier 3 but no one has called. I have done everything they asked. Used blacklist, disabled virus scan, even used in another computer. Still same problem. When I put in dvd player - Mitsubishi DD4001, it says "no disc". Any suggestions would be greatly appreciated.
