the question is already in the title
AFAIK the NEC/Sony/Optiarc-factories are bought by Liteon. Is the Optiarc BD-5730S a rebadge of a Liteon or re-badged LG/TSST/QSI?
If I remember correctly, the BD-5730S is a Blu-Ray burner based on a NEC/Optiarc (now Renesas) chipset, so one of the few devices, if not even the only BD burner with Optiarc design.
Thank you, Liggy, for the info
I searched for the 5730s and found also the 5740H. Any ideas which design this writer is?
