DVD burn speed confusion!

Hello all,

I am REALLY confused about my Taiyo Yuden DVD burn speeds and the quality of the different burn speeds of the discs. I have a NEC 3500AG Firmware 2.07 I’m using DVD Identifier as well as Nero to identify the media codes.

Why do my Taiyo Yuden (TYG01) 4x discs give me burning options of 2x,4x,6x & 8x?
Why do my Taiyo Yuden (TYG02) 8x discs give me burning options of 2x,4x,6x,8x & 12?
Why do my Taiyo Yuden (TYG03) 16x discs give me burning options of only 2x, & 4x only?
I have read that the TYG01 disc are the best (of the three above)–is this true?
What burn speeds should I be using?
Also I bought from Supermedia Store what where suppossed to be TYG01 discs and was sent TYG03 discs instead. Unfortunatly because I thought they were TYG01 (because I could only burn at 2x or 4x on my burner) I burned about 30 of them and sent them out. All were checked in my set top player and seemed to work fine–am I in trouble here?
Any input would be much appreciated.

The firmware and it’s media support decides here about the speeds.

The burner manufacturers decide that a particular media can be burned successfully at certain speeds.
In the case of TYG01 & TYG02 they reckon that the quality is good enough to step up the max burning speed by a notch over the rated speed.

In the case of TYG03, the firmware does not recognise this media so offers just the low default burn speeds of 2 & 4x. For this media you need to try & get a firmware update from NEC. You won’t get the best burn with these until you can get firmware that has a defined write strategy rather than the default. That doesn’t mean it’s bad, just not the best.

For burn speeds , start always at the rated speed.

I’ve always been a little leary to update my firmware. From what I’ve read it sounds like it can be a little tricky & if not done correctly you can mess up your burner. Would I go to NEC for the latest firmware? Does anyone have any tips on how to update firmware in as safe a manner as possible?


Yes go to NEC. Your firmware is way out of date. Get the new one here .
There are instructions included with this but essentially don’t have anything else running & don’t power off during the update. Once done , reboot.
If this doesn’t work , as in refuses to update , then there’s plenty of modified firmware that will work.
