Speed change on Blu Ray Burn

[fluke281]

I believe that I know the answer but anyway---- I set the burning rate for 25 Gig Ritek bd-r at 4.0 times and it reverts to 2.0 after a few minutes of burning. I suspect that it is the cheap media that I am using? thanks.

The drive can burn the disc at certain speeds specified in the firmware for different media.

 

The speed of burn can fluctuate during the burn.

 

A log would show us more info.
