Just bought a new iMac 20'' 2.4 duo core 2 g with Leopard. I have a Sony dcr-sr42 camcorder. The first day I started my computer imovie etc.. recognized and played the Mpeg2's from the camcorder without difficulty. The next time I tried it wouldn't. In the interval I installed paralels with xp several times as it would crash after I loaded microsoft office and other software. I also have upgraded to the latest quick time and downloaded imovie06 Somehow in all this my imac no longer recognizes mpeg2 so I think I either lost or damaged the mpeg2 codec that must have come with my computer. I am unable to download software (mpeg2 codec) from the apple site for free as some posts suggest (Greyed out for some reason) Is there a way to get the codec or reinstall the original config files from my Leopard install disks without having to do a complete reinstall of everything? Thanks for the help!
