    I have a large project that I want to make a dmg file of, but I get this message prior to creating the image:

    "If you use a disc burning utility to burn a double-layer disc image, the DVD may not play well in some DVD players. For best results, use iDVD to burn double-layer projects directly to a DVD."

    However, I don't know how to burn a dual-layer DVD in iDVD from a dmg file. Having searched around, I don't think it can be done. I have other dmg files and cannot import or open them into iDVD (unsupported format).

    So, how can I save my large dual-layer project to my external drive and be able to make a DVD copy in the future?

    Not sure if that's what you want to do, but you can use Save as Disk Image under the File menu, and then burn a DVD using Disk Utility (in DI, open the image you created in iDVD and choose Burn from the Images menu).

    If I burn it from a dmg file in Disk Utility, it may freeze in some DVD players. That's what the error message was referring to. It recommends using iDVD to burn dual-layer discs. However, iDVD won't import or burn from dmg files.

    I just don't know what the best way is to save my iDVD project (dual-layer) so I can burn extra copies if I need to. If I archive it, it will be almost 50GB! If I save it as a disc image (dmg), it won't be able to burn to a DVD without having free problems in DVD players.

    Do I have to use Roxio Toast for this? And if so, which is the oldest version that would do it?

    Should this thread be moved to the Digital Video forum?

    I guess (or hope) that you have solved your problems by now...

    However, one comment: I'm not so sure whether you should freak out about the warning message from Apple. It might just be some half-legal stuff, to be sure that someone using a good mac but a faulty dvd-burning software built-up by a 9-year old kiddo, would not affect Apple's reputation in digital video.

    All DVD-players are different, and I suppose that, even following the best advices, you might end up with a loosy player somewhere not accepting your dvd.

    Additionally, Toast could be a better tool than iMovie/iDVD. It has more options. In my case (with Toast 7.x), it even encodes the video from an iMovie project better than iMovie/iDVD! (But the menus are less fun).
