[QUOTE=Uncas1;2239871]I’m not too sure what you mean by drive… The recorder is called a Slimtype DVDRW SSM-8515S and the MID code for the discs are CMCMAG D03. I tried recording on another laptop with a different OS using different burning software and got the same results btw.[/QUOTE]
Slim-type laptop DVD burner are in most cases very mediocre DL media burners, especially with not so good and inconsistent DVD media like CMCMAG D03. You should try some Verbatim DVD+R DLs, they are the best DL discs around.
Or you may buy an external USB enclosure and good DL burner (Pioneer or Optiarc), which should handle even B-grade quality media like CMCMAG D03.
