I recently upgraded two DVDs in my PC to the AD-7190 and when I found no joy trying to burn at 16x I flashed their ROMs to the most current v1.04. Still finding no 16x joy I delved further and found (through DVD Info Pro) that the Ridata DVD+Rs that are packaged as 16x do not contain an Available Write Descriptor for anything other than 4x and 6x which are what Nero allows me to burn at.

I am not familiar with troubleshooting burn-speed problems. Any dummy can flash a ROM, I proved it, but my question is does an Available Write Descriptor for 16x have to exist on the media for me to be to be able to burn at 16x? Like I mentioned, I purchased these Ridata DVD+R thinking that the big [B][I]16x

[/I][/B]meant that was their burn speed… Thank you for any advise you may be able to provide.

Use better media like [B]Verbatim[/B] & be happy when it works.

Thank you chef I will go with the Verbatim’ DVDs from here on out. It’s funny that both of my old DVDs were 4x and I never had to even think (works well when I think not) about which media to buy and now I have these faster drives and I barely gained any speed - except that I can now have them both burning at the same time, Nero always crashed when I tried that trick before.

For further reference, does the ‘Available Write Descriptor’ have to be present in order to burn at that speed? Am I correct in guessing that this is where Nero (and other) programs get their burn speed data from?

Thanks again.

The writestrategy used for burning is chosen from the firmware (inside the burner). The media/MID is also an important factor, but also the real quality of the disc is a big factor.

If it works with Verbatim & TY (any burner should), then you could also try with other brands.
If there is no write descriptor/strategy present, it will fall back to standard speeds & strategies like 1x/2x for DVD-R/W and 2.4x for DVD+R/W…
