Recovering from Threshold

[dbminter]

When excessive disk writing activity occurs during a DVD-R burn, ImgBurn drops the writing to the disc to 0x until the threshold recovers.  On Verbatim MCC DataLife Plus 16x DVD-R, when writing to the DVD-R resumes, ImgBurn caps the writing at 8x maximum.  It has done this on both the LG WH16NS60 BD burner and the ASUS BW-16HT BD burner.

 

My question is: is this hardware dependent or something ImgBurn does itself?  Is the drive maxing out at 8x itself or is this an ImgBurn cap set by the software because of the hard drive activity?

 

Thanks!
