I guess this is really for any computer, I would just like to see the difference mainly between a new iMac and Macpro. I kind of brought it up in this thread http://forums.macrumors.com/showthread.php?t=255816 but there weren't numbers from the macpro. my iMac g4 1.0ghz 512mb, 10.3, ilife 06 etc. What i made: a 2 hour movie (made in imovie with no transitions, 2 titles) iDVD menu without scene selection. Time to encode, compress and burn: 9 hours (everytime) I am hoping some other people will post there times up here, especially the mac pro. Just try to include the computer setup, mac osx, length of movie and time to burn please.
