Sorry, ImgBurn has nothing to do with ripping/re-authoring protected DVDs (long way of answering "no" to your question) and we are not the sort of site that gives advice on ripping - particularly DVDs with advanced protection.
If you have a problem burning a disc with ImgBurn, by all means, ask a question (posting a log in the process). But please do not ask us to help you back up copyrighted content.
You need to start off the burning with "a good rip". As for layer break positioning, there's a guide on that.
