i have both of this programs, 1clickdvd(not pro) and clonedvd2. i only do main movie only and since i consider 1clickdvd's ripping(not to be confused with decrypting, which 1click is not) capabilities the best there is, i use it most of the times. i rarely use clonedvd2, i'm not quite convince its picture quality when large amount of compression is to be applied. by the way. there are not better transcoders than shrink and recode2 when speaking of large amount of compression. when doing main movie only, 1clickdvd does a great job, so it is my software of choice most of the times,.
