1. Change up the speed you're burning your DVDs at. If you're trying to burn at high speed, it might be too much for your computer to handle, so change it to a medium or slow burn speed by going back to the DVD page and select 'Add Pictures and Videos.' Then change the 'DVD Burner Speed' box to a lower speed.
2. Close out all other programs while you are burning your DVD, and don't open any programs during burning. This can give you the memory needed to burn correctly.

3. Take out any unnecessary, running hardware that's connected to your computer, such as an MP3 player that's charging on your computer. This will also help the burning process go along.
4. Defragment your computer files by going to the 'Start' menu on your desktop and select 'Computer.' Once in the Computer location, right click on your main hard drive (most likely the 'C:\' drive) and select 'Properties.' In the Properties box, select the 'Tools' tab, and then hit 'Defragment Now' to defragment your computer and clear up space so that your burning will go faster.
