[QUOTE=KTL;2093431]FYI, these are TEST firmwares, not official ones, so you will be relinquishing any warranty claims. You should try to burn a few discs with the stock firmware in there.[/QUOTE]
Sorry, but I disagree with this. This firmware has no support other than using the thread here at cdfreaks, but the firmware is official test firmware from LiteOn/PLDS and the warranty is still valid. If the drive should fail for some reason, just flash the drive back to standard firmware, if possible, before returning the drive, to avoid confusion.
I’d suggest that you use this latest firmware in the thread I linked to: DH20A3H - YV68 HT717 H12X
It’s very good firmware, with excellent media learning ability.
Make sure you check out the Settings Utility to get the best from the firmware. I normally enable all options but you may wish to leave overspeed off for the best results.
