Sorry. It is the first post we received from you. Please eject the original DVD, then restart your computer, and close all the other applications and try the following steps to shrink the DVD again.
1. Copy the DVD to your hard drive without compression. Please choose 'To Hard disk...' from Destination dropdown list to select a folder on your hard drive as the target. And please click "No" when our program prompts you to compress the DVD or not.
2. Compress the DVD from hard drive. Please choose 'From hard disk...' from Source dropdown list to select the "VIDEO_TS" folder of the DVD as the source. And please click "Yes" when our program prompts you to compress the DVD or not.
Hope you could succeed. If still fail, we need you to insert the original DVD as source and click the icon on the left top of the window of Ideal DVD Copy, then click "Export bup files" to export a .buz file and manually attach it to our support team
support@idealdvdcopy.com . We will help you.
