I just got a new Power Mac G5 and to my dismay Final Cut Express 2.0.3
refused to start. It complained that I did not have an AGP graphics
card. I searched the web to no avail. Everyone just said to upgrade to
FCE 3.0.1. I decided to take a peek in the package contents. I found in
"Info.plist" a section called "AELRequiredIOPCIDevice". It was set to
"AGP". I just replaced "AGP" with "PCI" and presto, Final Cut Express
2.0.3 started fine. I'll now keep my $99 thank you.
