I just got a new iMac a few days ago and I am new to Macs in general. I am trying to edit a .mpeg file (from my old PC) in IMovie in order to eventually put it on a DVD. Quicktime will open the file (I dont have QT Pro), but IMovie will not allow me to open it. Is there any way to edit a .mpeg file in IMovie, or is there some software that someone might recommend downloading or purchasing. I have read a few posts about Toast Titanium- will this do the trick? Sorry for all of the questions, I am still very new to Macs. Any help will be GREATLY appreciated!
