Welcome to the Forum.
PHILIPSC08 and CMCMAGE01 DVD+R Media is manufactured by CMC Magnetics Taiwan and is noted to be cheap poor quality Media which produces unacceptable results.
RITEKR03 DVD+R Media is manufactured by Ritek Taiwan and is slightly better Media than CMC Media but it is noted for reflectivity degradation problems.
To ensure consistent quality error free results use proven known quality Media (Verbatim or Taiyo Yuden) and the newest most current up to date DVD Burner Firmware.
