I have hdv (m2t) and dv (avi) capture files on my pc. I'd like to convert them to 720p files to stream to my appletv. My daughter has an iMac that I am thinking about using since I'm guessing it'll be easier to do the conversion with it. Will the imac be able to read the m2t and avi files from my pc? I am pretty sure that I can network them over to it. Any tricks to creating the 720p files in imovie, or is it pretty straight forward?
