I use a blu ray burner drive brand like LG HL-DT-ST BD-RE-BH16NS40 SCSI bought in late 2013. I want to burn HD video in 1920x1080 21Go to m2ts. After burning 5 discs I give up because all have problems reading on Pc and blu ray players (locks the reading at the same places or stop burning 90% of the film). Performing the same engraving on BD-RE / 25GB rewritable brand EMTEC perfect result in 1 hour. After searching the internet I read the report of Trappes Testing National Laboratory for the National Archives that BL type LTH, including Verbatim brand are totally unsuitable for keeping records because of unreliability in the engraving according engravers used, as well as premature aging over time (3 to 5 years)
