The only thing that matters is the length of the video. You can fit an hour of video on a single layer disk, and you can fit 2 hours of video on a double layer disk. The 8GB does not matter, because your DVD authoring program (such as iDVD) will compress the file and convert it to MPEG2 to make the DVD.

If you are using iDVD there are 3 encoding settings for burning a DVD. The Best Performance setting will provide up to one hour on a single-layer disc (as referred to by AppleMan). The High Quality and Professional Quality settings will provide up to a maximum of 2 hours on a single-layer disc. Approximately double these times will be available for double-layer discs.
See the following information, as extracted from iDVD Help:
When you select Best Performance, iDVD encodes your video in the background as you’re working on your project instead of waiting until you burn it. This can significantly reduce the amount of time it takes to create a finished DVD. This is a good choice if your project is an hour or less in duration (for a single-layer disc). You’ll finish your project more quickly, and the encoding quality will be excellent for the amount of video you have.
Best Performance encodes your video at a preset bit rate that produces great quality for projects that can easily fit on your disc. If you have a larger project that needs to be squeezed onto a disc, you should select one of the other encoding options.High Quality
This is the best encoding option for larger projects that are between 1 and 2 hours long (for a single-layer disc). With this setting, iDVD chooses the best bit rate possible for the amount of data you need to fit onto your disc. It’s the only option that “squeezes” all the data onto a disc at a bit rate that ensures a high video quality in your burned DVD. Because iDVD does not encode in the background with this option, it takes longer to burn your disc. The encoding process begins when you burn the DVD instead of when you start working on your project.
The Professional Quality option uses advanced technology to encode your video, 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 time.
