I have been a PC guy for many years and just recently switched over to mac. In general its been a good experience. Mostly its just learning where the equivalent setting of feature is on the Mac verse the windows machine. I did run it a problem that I am confused about. It appears that iMovie cannot support mts or m2ts file format. I asked Google and sure enough iMovie doesnt support AVCHD (mts or m2ts) files, but will convert them if they are in the correct folder structure. So now for my questions: Who else has run into this problem and how did you solve it? Download a program like Video Monkey or purchase a Video converter? Do you lose any video/audio quality? What is the best format for HD video that works with iMove? How do you keep the mts files for future use? Is there or is anyone working on a plug-in for iMove or iPhoto to utilize AVCHD format? Do you think Apple will ever fix this lack of support?
