Difference between MTS and M2TS
Video file recorded in the AVCHD folder in DV hard drive is MTS file, which turns to a M2TS file after transferred to computer hard drive via PMB.

The AVCHD format records video using the MPEG-4 AVC/H.264 video codec, and audio in Dolby AC-3. Other than the video and audio codecs, AVCHD also contains menu navigation, slide shows and subtitles. The menu navigation allows access to individual videos from a common intro screen, the slide shows consists of a sequence of AVC still frames accompanied by background audio track, and the subtitles are used to timestamp recordings.

Though both MTS and M2TS are file extensions for the same AVCHD and both support 720p and 1080i HD video formats, there is a slight difference between the two. In the M2TS file, the video file is saved in the high definition Blu-ray BDAV format. Video data on the Blue-ray discs can be saved in one of the three video codecs – MPEG2 Part 2, H.264/MPEG-4 AVC, or SMPTE VC-1; and the audio data in Dolby digital, DTS, or the uncompressed Linear PCM. The M2TS file extension is written as “xxxxx.m2ts” where the “xxxxx” are a five digit number corresponding to the audio-visual clip.
