  • Hey Jeremie-

    Are you looking at the scale in Nero Video or the size after it's burned? In the first case, what's shown will vary with the version of Nero Video.

    I assume you're opening Nero Video and selecting DVD, DVD-Video. After you import a video, click on Options, Recording Format Options. Disable SmartEncoding. Does that change the size?

  • Jeremie,

    At normal DVD quality, it takes about 1 GB to encode 20 minutes of video. DVDs are encoded using MPEG-2 compression - much less efficient than AVC. How many minutes long is your video?

    You can use the free MediaInfo program to display information about the video.

    Here is the MediaInfo data for an AVC file that occupies about 1 GB on a DVD:
