Will iDVD 6 burn a dual layer with 3rd party burners

Question

G'day from Oz.
I've posted similar to this under the iDVD 5 forum, as this forum wasn't started, but no answer yet. Hopefully people browsing here have updated to iLife 6.

"Go for the burn.
Once you finish your DVD masterpiece, only one step remains. Burning it. Thanks to stellar compatibility, iDVD 6 makes the big burn a painless process.
With support for a wide variety of DVD media formats — including DVD-R, DVD-RW, DVD+R, DVD+RW, and DVD+R DL — iDVD 6 teams up with a compatible SuperDrive or third-party DVD burner to offer you more media options than ever. You heard right: iDVD lets you burn using compatible third-party DVD burners.
iDVD even lets you archive projects as disc images. Saved this way, your projects are extremely portable and take up less space, and are read-only. What’s more, they’re already encoded, so you can quickly burn them to DVD whenever you have a free moment or a burner handy".

** Note the 'DVD+R DL'. **
Does this mean that burning a dual layer project with dual layer 3rd party burners will be supported?
I've updated to 10.4.4, but my Sony dual layer burner still shows as 'Burn Support: Yes (Unsupported)', in 'About this Mac'. The 'unsupported' means 'no dual layer burning' as far as I know. Also, I believe dual burning is only supported from within the OS itself? True or not?
Let's see who's first to try the new iDVD 6 out with a 3rd party burner & dual layer disk. If it works, it means iDVD 6 really does support third party burners.
Please post results.

G'day.
Further to my post a week ago re this subject, from the iDVD 6 help pages.

Newer SuperDrive optical drives in Macintosh computers can burn discs in DVD+R DL (Double Layer) format. Double-layer discs store almost twice as much content as single-layer discs, making them a great choice for large projects.
To see if your computer's SuperDrive can burn DVD+R DL discs, choose Project > Project Info. If you see 8.0 GB (Double Layer) in the DVD Type pop-up menu, you can use these discs for your project.
To burn a project to a DVD+R DL disc:
Choose Project > Project Info and choose 8.0 GB (Double Layer) from the DVD Type pop-up menu.
Select the encoder setting you want to use. If you have more than 120 minutes of content, select Best Quality.
Click OK.
Click the Burn button (shown above).
Insert the disc when you see the prompt.
If your project is small enough to fit on a single-layer disc and you insert a double-layer disc, you see a dialog giving you the option to change the media type. You can cancel the burn and start again, or insert a new disc and continue.
You should always burn double-layer discs directly from iDVD and not from a disc image. Double-layer discs burned from a disc image may cause playback issues in some DVD players, such as freezing during playback.

The last sentence is interesting, as the commonly suggested method of burning Dual layer discs is by first creating a disc image, then burning with Toast or Disk Utility.
Also, my Sony shows up as supporting 8 Gig in iDVD 6, but still shows as 'unsupported' in System Profiler.
