Re: PX-716SA growisofs won't write DVD

updated to latest firmware and used the media that came with the drive and it burned fine. Now I guess I just have to find media the drive likes. rather dissapointing in that its a plextor, I'd expect it to burn to anything, but at least now I know it works!

Have you tried other quality media after the update, and/or manually reducing the speed? I've had pretty good luck using "computer show" media, white label stuff with undocumented media codes, as well as quality media for more demanding uses, of course.

thanks,

is there a way to disable the drive from doing any media check and just
writing?
No, because the drive hardware needs to be tuned by the firmware to
produce correct results. But looking at the output, you also support 6x
writing in your drive. I would try writing this media at 6x, since it's
a supported speed. That's about the upper end of how fast you write a CD
at 48x, as a data point.

It may be that the firmware indicates it can operate at 8x, but can't,
at least with this media.

 It seemed like a good idea at the time
