DVD+ is superior to DVD-

I don't agree with all of the their comments.. especially the part about defect management.

As I think defect management might one of the key feature not for the market success but for the quality of the products, both from an hardware point of view (media and recorders) but also from a software point of view, I would be interested in hearing more about your opinion.

Personnaly I've seen that implementing support for MRW and DVD+RW does not require too much efforts, while DVD-RW DRTDM technology is more some kind of very tuned by difficult things to do. And I fear that difficulties will lead to bugs/instability, which is really not what is the target when the key is the data integrity.

Additionnaly, Microsoft as one of the founder of MRW might be likely to support DVD+MRW vs DVD-RW (but maybe I've missed some announcement from Microsoft).

As you were apparently more from the side of DVD-RW for defect management, I would be happy to hear your comparison between both models here.

David,

I just found it odd that the author said that hardware based defect management hasn't been implemented on the DVD+RW drives available today. Yeah, I've seen some references to defect management and DVD+MRW, but this has been an advertised feature of the DVD+RW format since day one.

Again, the author says that there's a lot of info not privy for the public, so I might be missing something. If he's right, this is one of the biggest cases of false advertising I've seen.

Anything you can share on this? As the InCD product manager, you'd probably know better than anyone.

G... I'd like to, but you might bet this is under NDA.

I guess that DVD+RW was placed on the market without hardware based defect management for time-to-market troubles, considering that DVD+R have already been released after DVD-R.

I now understand the current superiority of DVD-RW defect management over DVD+(M)RW, as DVD-RW is available here today, when DVD+MRW is still some "one day in the future" feature.

As InCD 4.0 is today already supporting DVD+MRW (as the MRW is a very nice specification abstracting software from physical related things), I am strongly looking forward to see these devices on the end-user market. I guess that the complexity it saved for software developers have to be paid by firmware engineers.

You mean you are also waiting for a working DVD writer with DVD+MRW support.
