Duplicating DVD-9 - more duds than DVD-5?

[sdsumike619]

I'm aware of the incompatibility issues with selling duplicated DVD-5 DVDs.. Over the past several years, out of over 1000, there have only been a few bad discs reported. My question is, will that incompatibility percentage rise if I were to start getting 4 hour DVD-9 duplicated? Or should I expect essentially the same number of bad discs as in the past?

On recordable media ??

HIGHER/MORE!!!!

Double Layer recordable media has lower compatibility than single layer recordable media on standalone players.

Pressed you should have no problems.

Noahtuck is 100% correct. If you must duplicate, my suggestion would be to use Verbatim DVD+R DL discs as they are the best of the DVD+R DL discs out there. I cannot recommend other brands, nor can I recommend the DVD-R DL discs. The DVD-R DL format is not as compatible as DVD+R DL (and DVD+R DL is not as compatible as any recordable single layer disc), but there are a few weird players that will play DVD-R DL and not play DVD+R DL at all. If you won't use Verbatim, you'll save money but the discs will be of much lower quality. Verbatim currently is making their non-hub printable DVD+R DL discs only in India now and there is much debate about the quality. Nero's CD/DVD Speed tool seems to indicate that these discs are somewhat lower quality than the old Singapore made discs, but still pretty good quality. However, many insist that the India made discs are pure garbage.

Paying for your discs to be professionally pressed is the only way to ensure that they should work anywhere.

Of course your other option is to go to a commercial DVD producer and use pressed discs. But the costs will be high for small quantities. Other than that, even using the best brands of burned discs, you will always find some players that won't accept the discs. You might ask your clients what players they have or formulate a refund/warning policy that accommodates playback problems.

IMO, dual layer burned discs are still somewhat 'experimental'. That shows in that Verbatim DL+ seems the only product that is 'fairly' consistent.

Myself, I would stick to DVD-5 burned discs, even if it takes two for the amount of info. And use TY or Verbatim or similar good quality media, along with a good authoring/burning program(s).

Thanks for the quick replies.. Ok, that's what I wanted to know. Two two hour DVDs will be better then. I have some stuff replicated, but this next series is going to consist of several volumes and getting 500 or 1000 of each of these will be huge overhead. I have a great deal on duplication with my supplier, how I got it, I don't know ($1 per disc!) packaged and shrinkwrapped so I think I'll stick with that..
