Yes, you are most definitely correct. All you need is the Slysoft combo. Furthermore, CloneDVD and AnyDVD are updated to handle new problem protections and DVDD and Shrink are no longer updated. People formed love affairs that have lasted years with both these freewares so one has to give credence and allow respect for the fondness old timers hold for these two freewares.
When you graduate to dual layer burning, you may want to revisit DVDD (or it's new incarnation ImgBurn) for its ability to create easy ISO files. But, if you feel more comfortable staying with Slysoft, CloneCD has just been updated to do the same thing.
