Apple hasnt fully dropped support for PPC yet. the requirements for Leopard are 867 MHz G3 or better.
Everything in Leopard will work but DVD deinterlacing and a transparent menu bar (depends on Mac).
However, in iLife '08 you can't use iMovie '08 (since it was brought up).
It's a great upgrade from Tiger for a PPC machine. My 1.5GHz 1.25GB 12" PB runs better with Leopard than it did with Tiger here as well.
o ya its not idvd its imovie
or is it both?
i have iDVD 08 on leopard on my 1.33ghz powerbook
G4 you mean?
