    Hello,

    I recently burned a couple of .avi and .mpg video files to a dual-layer DVD+R as a data disc (DVD-ROM) using the program "Burn" which is, in essence, a nicer front-end to Mac OS X's burning capabilities.

    However, after burning, the video files on the disc are now unplayable. It seems like they are corrupt.

    Am I doing something wrong? Do dual-layer discs need special settings to make it work as data discs?

    What model Mac do you have? Only Macs released in the past 3 years or so have DL-DVD burners. You can see what formats your burner supports by going to :apple: -> About This Mac -> More Info.

    Barring that, it could be that the burn just failed. Try burning again. You shouldn't have to do anything special to burn a DL-DVD.

    My Macbook is only 1.5 years old. I just checked the System Info and it seems to support DL burning.

    I just tried burning to a single-layer disc, and I got the same error! When I try playing the video file from the disc, Quicktime says "The movie could not be opened. The file is not a movie file."

    Meanwhile, the same video file plays fine on my HDD. Furthermore, burning any other kind of data seems to work fine. When I try to copy the .avi file off of the DVD back to the HDD, it says "File could not be copied"

    I should mention that the .avi file is about 2.5GB. Is there some sort of file-system restriction on DVD-roms for files this large?

    Edit: According to this post: (http://club.cdfreaks.com/f48/burning-large-files-dvd-157688/), the Joilet/ISO standard for DVDs do not support files larger than 2GB. I will try burning again with the UDF standard and see what happens.
