Maybe my project, a 139 minute dance sequence (Final Cut Express), is just too long for a DL disc created in iDVD. I've tried both likely encoding settings, High Quality and High Performance, and I've cut the menu down to the bone. I've read the thread and was told that burning to disc was more reliable than burning to disc image. Nothing seems to work. Except I was able to burn a DL-disc on a 3rd party system, but that meant going through another compression with unacceptable results. Before I try Roxio, in which I believe you can custom set bit rate, I'd like to give iDVD one more try. Those of you who have been through this, any pearls of wisdom?

Thanks (forgot: iDVD 7.1.2, Verbatim DVD+RDL, Apple 2.7 Intel i5, Mac OS 10.7.5)

    Try setting the encoding to Professional Quality - that works for me with dual layer DVDs:

     

    iDVD encoding settings:

     

    http://docs.info.apple.com/article.html?path=iDVD/7.0/en/11417.html

     

    Short version:

     

    Best Performance is for videos of up to 60 minutes

     

    Best Quality is for videos of up to 120 minutes

     

    Professional Quality is also for up to 120 minutes but even higher quality (and takes much longer)

     

    That was for single-layer DVDs. Double these numbers for dual-layer DVDs.

     

    Professional Quality: The Professional Quality option uses advanced two-pass technology to encode your video (The first pass determines which parts of the movie can be given greater compresson without quality loss and which parts can’t.  The second pass then encodes those different parts accordingly) , resulting in the best quality of video possible on your burned DVD. You can select this option regardless of your project’s duration (up to 2 hours of video for a single-layer disc and 4 hours for a double-layer disc). Because Professional Quality encoding is time-consuming (requiring about twice as much time to encode a project as the High Quality option, for example) choose it only if you are not concerned about the time taken.

     

    In both cases the maximum length includes titles, transitions and effects etc. Allow about 15 minutes for these.

     

    You can use the amount of video in your project as a rough determination of which method to choose. If your project has an hour or less of video (for a single-layer disc), choose Best Performance. If it has between 1 and 2 hours of video (for a single-layer disc), choose High Quality. If you want the best possible encoding quality for projects that are up to 2 hours (for a single-layer disc), choose Professional Quality. This option takes about twice as long as the High Quality option, so select it only if time is not an issue for you.

    Use the Capacity meter in the Project Info window (choose Project > Project Info) to determine how many minutes of video your project contains.

    NOTE: With the Best Performance setting, you can turn background encoding off by choosing Advanced > “Encode in Background.” The checkmark is removed to show it’s no longer selected. Turning off background encoding can help performance if your system seems sluggish.

     

    And whilst checking these settings in iDVD Preferences, make sure that the settings for NTSC/PAL and DV/DV Widescreen are also what you want.

    Not exactly so. Saving as a disk image gives you the opportunity to check that the final DVD will work (by playing it in DVD Player or VLC) before committing to an actual DVD. That can save a few 'coasters'!

     

    Also, if you need more than one copy, you save having to render or encode the iMovie project again.

     

    It is also the best way to back up your iDVD project.

    I'm very perplexed as to why I couldn't get iDVD to burn a DL Disc

    Me too. It should work a treat. Try saving as a disk image, then burn with Toast (my normal workflow).
