How much can I fit on a disc?

Answer:

The amount of video you can fit on a disc depends on both the disc type and the video quality.



DVD durations

These are typical DVD-Video durations for different disc types at different video quality
settings:




Video Quality 4.7 GB DVD 3.95 GB DVD
Best 60 minutes 50 minutes
Better 120 minutes 100 minutes
Good 180 minutes 150 minutes

These durations are only for video captured in MyDVD. If you use files from other sources, such as AVI files, MyDVD converts the files using the "Best" quality setting, which means you can fit about 60 minutes of video onto a 4.7 GB DVD.



Note: The video quality level depends on your PC's speed and graphics processing abilities. Slower PCs may be unable to create video at the best quality setting.



VCD durations

VCD recordings have only one quality setting -- Good. You can fit about 60 minutes onto a 650 MB CD or 65 minutes onto a 700 MB CD.

Does DVD+RW support dual layer discs?

Answer:

Will there be DVD+RW discs with a higher capacity than 4.7 GB?

Answer:

No. DVD+RW has been designed from the start to be compatible with existing DVD players, so creating a disc with a higher capacity than the 4.7 GB defined for DVD-Video and DVD-ROM would render these discs to be incompatible with existing players and drives.
