1. Using PowerISO to convert a DVD9 retail into an ISO file without shrinking. Could there be any sort of regional encryption issues that would block me from doing that for certain DVDs? Is it necessary to have AnyDVD running in the background? 2. I have PowerISO. When I back up my DVD9 into ISO, I do not shrink them. I keep them at DVD9. Say I would like burn one of my DVD9 ISO files onto a blank DVD4 DVD. What can I use to shrink the DVD9 ISO file into a DVD4 ISO file? 3. I use Easy CD-DA Extractor for all of my music file conversion, CD ripping, and CD burning needs. Is this a good choice? 4. I would like to convert all my downloaded movies/videos into avi filetype. Is there any good program that does that? How can I create a playable movie DVD out of an avi file? How can I convert a DVD movie into an avi movie file?
