(how come it never uses 100% of both CPUs?) it only uses about 1/2 of the total power...is there a way for it to put all system resources to this one app, cause i wont be doing anything else? I am trying to have my computer encode video, from a project I make on imovie. I used iDvd to burn the project. It goes through all the rendering/encoding, and it takes it an HOUR! This is a dual 2.7GHz powermac! The video is only 1:00 long! Then, the part that really annoys me is, once it is finished rendering, and all that stuff is complete, it goes to burn and the disc doesnt even spin up in the drive, when it says "There were errors found in the burning process"...or something like that?????? What is/am it/I doing wrong??
