i don’t use dvd idle pro, but here’s the basic rundown.
you need a program that will decrypt. DVD Shrink and DVD Decrypter were both good decrypters in their day, but unfortunately their day has passed. Neither is developed any longer because of legal reasons.
you need a program that will shrink the dvd to fit onto a single layer disc. This is where DVD Shrink comes in. It allows you to remove previews/extra foreign language soundtracks, etc. etc. and then it compresses your final product to a useable size.
Shrink doesn’t have a burning engine of its own, but you can make the output either files or ISO and use whatever burning program you prefer to burn whatever format you choose DVD Shrink to create.
I personally use Anydvd for on the fly background decryption and CloneDVD to both shrink and burn. In my mind it is the simplest solution. The above explanation includes free software and a little more work. The Anydvd/CloneDVD2 combo costs money, but is worht looking into. you can get a 21 day free trial of both from www.slysoft.com and see if you like it.
you’re really going to have to try things out and read guides for the programs to decide what you like best and what works for you.
there’s a huge learning curve when you first start out, and you have a lot of reading ahead of you before you know what you’re doing. Once you test out some programs and do some research then you can ask more educated questions that we can answer more specifically.
for now, you’re asking “how do i burn a DVD” and there are TONS of different ways to go about it.
