Support program problems

Just dl the 312 trial of copytodvd. After starting i clicked on dvd to dvd & was taken to dialog box which stated i needed additional dl to do this. I thought the program would use my installed copies of decrypter & shrink to do the heavy work & then burn. However i cannot find a way to point the program to these files & it apparently does not search for them. Any suggestions. Thanks
