I agree with naquaada and B.Hast... This app has almost lost its usefulness to AMD users as we now have Zephyroth to thank for the AMD Software Update. In the past, the only reason for Marvin's Utility was to make sure that if you updated your hackintosh using the regular Apple Updates, the cpuids would work out to allow AMD users to still run OS X and its Apps. Normal Apps don't really need this (except possibly a few like Toast mentioned above) as most are now Universal or could be run using Rosetta. iDVD could be Xslimmed to take out PPC code and languages you don't need, possibly making it faster and thus more reliable. IDK for sure though.
