I guess you meant AVCHD. As I understood, this is MPEG4 AVC video (aka H.264) in M2TS container. Since I don't have an actual file of this format to test, I can't be sure, but people say if you install Haali Media Splitter and CoreAVC video codec you'll be able to open such files in different DirectShow apps including Video Enhancer.
