This DVD has a new copy protection. We've uploaded the fixed files to our server. But we found Disney basically manufacture them the worst they possibly can. And since Ideal DVD and other ripping programs need to read the whole content of the disc, sector by sector, and standalone players are more error-tolerant and can skip over bad sectors, this makes it so they will play fine, but will get read error when copying and ripping. On this occasion, please just click "Yes" to continue when our program prompt you read error occurs. If you finally get "too many read errors", please try to copy or rip it on other DVD drive or computer, maybe you can succeed.
BTW, before copying this DVD, I suggest you click the icon on the left top window of Ideal DVD Copy, click "Check Update" to ensure you have got the latest decryption files.
