OS XP After upgrade to 18.104.22.168, got message "Burn Failed, want to try again." Tried again and after copy process got message, "Copy Complete." Copy was defective and would not play in any of my DVD players. Tried to backup another movie and it showed "Copy Complete" but again the backup would not play in any player. After wasting 3 blank discs, reinstalled 22.214.171.124 and it worked fine. Apparently serious problems with new version. Any suggestions?
