I've got a NEC ND-3520A burner and a Lite-On LTD-166S DVD-ROM. I like to use the Lite-On to rip DVD's for back-ups to save my burner, but using DVD decrypter it only rips at 2x. The firmware is old, DS0E. I am leary to update to newer firmware as it can no longer be found on Lite-On's websites, and the drive otherwise works fine. Has anybody here found a reliable firmware that increases ripping speeds?
