“The main chipsets come from NEC, with part numbers NEC D63635GM and NEC C333500. The same chipsets are used in the TDK 1616N, the Pioneer DVR-108 and ASUS DRW-1604P.”
The TDK 1616 drive is a known clone but this info confirms that the Pioneer x08 is a NEC “cousin” (not a clone though).
The fact that some hacked firmwares burns DVD+R DL Ritek discs @4x and some @ 2.4x is interesting too. (DL 2.4X burn quality is better than 4X ! … I can keep my 2510 for a while …)
Strange crappy DVD RW burning though on some media
