How to convert AVCHD file to AVI format?

One of our users write us an email:

Hi, I bought a new Canon HD Camcorder ( Canon VIXIA HG20) that records videos in 1080i format with a *.mts extension. It said that it is encoded with AVCHD codecs. I want to play such files with my Windows Media Player or Quicktime Player. I don't want to spend extra hundreds of bucks for a professional avchd editor, so I am trying to find a free software that will convert avchd mts recordings to other common formats. How do I do this? It is annoying thing for newbies like me. Do you know of any such free software ?

I recommend AVCHD Converter. It converts mts files (actually avchd) to avi perfectly.

Supported OS: Windows XP/Vista/7 and Windows 8 丨丨 Mac OS X 10.9(Mavericks), 10.8, 10.7, 10.6
