Convert AVCHD/HDTV (MTS-M2TS) videos to AVI format

MTS or M2TS formats are MPEG Transport Stream used for blu-ray and for digital cameras. I've used a Sony camera to record a video and the result was a file with extension .MTS. After many tests I've found some tools to convert MTS format to another. First software is "xproc": this extract audio and video tracks from MTS with 2 output files (one .MPA and one .MPV). Second software is "ldecod" that convert MPV file to YUV. After this you can use "ffmpeg" for example to join audio and video(YUV) in AVI format.
