You will see NO difference and will get the same quality conversion using CCE SP or CCE Basic. It has the same encoding engine in them both. Basic is limited to 2 pass max (therefore of little Hollywood use), and a few minor differences. But otherwise, its a bargain at $59.
As for comparing Shrink to ReBuilder w/ CCE, they are similar but different products. In Shrink you change the compression of Extras, etc. while in ReBuilder you cant (at the moment, it is comming). Also, Shrink compresses the menus, while RB doues not. If a DVD contains a large quantity of animated menus (therefore large size) then these just included in a RB build un-compressed. RB also does not compress small VOB files (about 50 meg or less) This is why a Shrink conversion can have a slightly better compression compared to a RB build.
However, using CCE as the encoder the results are just so much better than the slightly less compressed Shrink equivalent.
Again, the layout of the DVD has a lot to do with it also. If you have a movie of 4.5gb and another 4 gig of extras, then just a main movie only with Shrink (reauthor) will give a final disk of identical quality to the original assuming no compression. But if you shrunk the whole DVD with both Shrink or RB, the result will be like chalk and cheese in RB's favour.
