Hello - We are experiencing a strange problem with iDVD in our computer lab.  During the burn phase, we get an "error during encoding" message.  I run a computer lab with 20 computers- all operating on Lion.  I do not get the message all the time - We are creating movies in iMovie, then sharing to iDVD.  I have tried using different discs, taking the movies from the media browser, slowing down the burn speed as well as changing to professional quality.  I have also tried saving as a disc image to the desktop...but I get the same encoding error message.


Please help!

    First create a disk image of the iDVD project


    mount the disk image and play with DVD Player to separate the encoding process from the burn process.  


    If you can create and play a disk image then the problem is with the burning and not the encoding. Also saves some disks from being coasters.


    Follow this workflow to help assure the best quality DVD video disk possible:

    Once you have the project as you want it save it as a disk image via the  File ➙ Save as Disk Image  menu option.  This will separate the encoding process from the burn process. 


    To check the encoding mount the disk image and launch DVD Player and play it.  If it plays OK with DVD Player the encoding was good.


    Then burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality.  Always use top quality media:  Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.

    Hi toad thanks for your suggestions. I had previously tried saving as the disc image however during that process I get the same encoding error message as well.  Any other suggestions??

    Then consider the post by Bengt regarding encoding errors in this topic: Stage 4 Multiplexing - Media error in...: Apple Support Communities.  Bengt is way more knowledgeable about encoding and such than I.
