Problem in transferring videos to Sound in MyDVD

When I am attempting to transfer videos to Sound in MyDVD, I can’t because I faced with an error message which is:
Could not finished the last command because: Could not make a thumbnail. You have to ensure that the appropriate decoder have installed. (DVDErr, -47010)
I use MyDVD version 5.3.0. It was previously installed in my computer and the operating system of my computer is Windows XP Home Edition.
Please, I want a solution.
