How to fix "Not enough space on the disc" Problem

To fix "Not enough space on the disc" problem, select Standard or High Quality from the bottom right corner of the main window of the program. This reduces the size of the file but also reduces the quality of the output file. The Best Performance option provides the best quality but is the biggest in size. Standard has the lowest quality but is the smallest.

If DVD movies size is much larger than the DVD 5 disc capacity (4.7GB), or if what you want the highest video quality, then burn movies to a DVD 9 disc (7.9GB). If you have not DVD 9 disc, you can still use the Best Performance option, but you have to split your DVD movies into two parts and burn them separately onto two DVD 5 discs. 

Tips: 1. Before burning, you can create an ISO file by going to Burn > Save ISO Image File and play with your media player to check the video quality.
          2. With the help of the blue bar at the bottom of the program, you can easily deduce the DVD movie size and ensure the size has not exceeded the capacity of the select DVD disc type.
