Hello. I know cucusoft, i came accross the software on the site: brothersoft, i am so suprised to find "imtoo" has been nvolved in their introduction about their dvd ripper, they worte:Cucusoft DVD Ripper is an easy used dvd ripping tool with high ripping speed...........and ImTOO DVD Ripper will automatically copy them one by one. i do not know why...
