There are 2 updates for iMovie and 1 for iDVD on Apple's website that I had to install, then they both worked perfectly. Ran marvin's on the App folder and it found a couple of cpuid's in iMovie so I patched them. Also Garage Band crashes the first time I launched it but I clicked ignore and re-launched and it works perfect every time now. Over all everything runs fine on my system (HP Pavillion a1600n updated graphics to a Geforce 7300 GS).
