I have had my laptop for about a year now and have been using its Toshiba SD-R6112 to burn dvds at 2x speed without any troubles. The DVD-R media I have been using until now is "Verbatim" (4x Certified 120min).
I have recently invested in more cheaper bundles of DVD-R (Almost 4 times as cheap) of brand names: "EMTEC" (1-4x Certified) and "Bulkpaq" (4x Speed DVD-1).
Using Nero I burn compilations with Verbatim media at 2x speed in roughly 30 minutes.
However when I use either of the two new medias and select a burning speed of 2x (Which is my maximum), the "Remaining Time" text says 30:00 (Approximately) but when that time has expired, the progress bar has only reached 50%. Therefore its as if I selected to burn at 1x speed.
Could anyone tell me the reason and/or explanation to why this happens? I appreciate any help you can afford me.
