I've never uses Dycrypter for anything but ripping. I used Shrink for some time until I found Recode which compresses and burns in one operation unlike Shrink which requires 2 separate cycles and creates a second set of files on the HDD. I haven't been using Recode for long but have no complaints yet. So, I guess the answer to my question is "NO" I don't need ImgBurn, at least not yet. Thanks.
