Dual Layer DVD Burner for Mac OS 9

Question

I always figured that the 1 hour burn limit imposed by iDVD was done intentionally to help sell DVD Studio Pro. Now having bought a copy of DVD Studio, I find that the limitation is actually imposed by the number of layers a burner is capable of writing.
My research leads me to believe that Apple released a dual layer burner for the MacBook but no mention of its comaptibility for other models.
So is there a dual layer burner available for other model Macs and equally important will it work with Mac OS 9.2.2?

Answer 1

Funny, the link provided and researched before posting here does show
the MCE drive* to fully support Apple software without Roxio and has a
30 day guarantee if for any reason (including no evidence of failure)
they will replace or refund your money. Less installation fees, if any.
The primary issue, from your perspective, is the need to run OS 9.2.2
and presumably boot native and burn with it. Otherwise, the product
will perform as indicated in their write-up.
{A call to Other World Computing is recommended, to see if they have
or know of a hardware replacement for what you specifically need.}
What they do say, in several places, indicating proper interface with
the Mac OS X system and applications, is:
*An MCE Exclusive (10.4+ required)
iLife '05+
Seamless integration with iLife, Mac OS X
The MCE 16X Internal SuperDrive Upgrade with Double Layer support is seamlessly compatible
with all of Apple's iApps including iTunes, iDVD, and iPhoto. In addition, it is compatible with Finder
Burning and DVD Studio Pro, Apple's professional DVD Authoring software.
These are often a choice for replacement hardware in out-of-warranty units.
And they often supersede the earlier hardware they replace, or match many
specs in new environments, depending on what product application's compared.
The earlier link to search results and product info direct from quality vendor sources
is a recommended path; call the actual company (note names of duration in resale)
or contact a regional or local parts vendor or authorized Apple repair center.
MCE's product, as listed, will do the job in OS X. It may work with Classic9 under X.
Good luck & happy computing!
