Appears to be THE answer to my BIG problem!!
Just switched over to a new iMac after several decades with PCs. Problem: 444 treasured home movie clips from a Sony HD videocam to import and convert. Sonys proprietary software can be difficult to work through, and is not Mac-compatible. The Apple store advised me to try iVI and voila .. 444 Sony .m2ts video files which seem to have converted seamlessly to .m4v files on my iMac. If the results are as good as they appear at first glance, Im extremely appreciative and impressed. Thanks folks!
