welcome to the forum. i recommend doing some research on the forums first. we can answer specific questions, but no one here is going to give you a step by step analysis of “how to copy a movie”
i can say that anydvd and clonedvd2 are very good programs especially for beginners. check the guides in the sticky threads at the top of each subforum
anydvd does not compress (transcode). it merely decrypts and recently, a ripper function was added.
clonedvd2 is what you need for compression.
visit www.slysoft.com for the official notes and help section and also 21 day free trials of each program.
if you have anymore specific questions feel free to post back here!
