MTS vs M2TS: Differences between HD camcorder AVCHD Formats

After shooting with my new Sony HDR-CX240 (1900x1080i), I imported the same file two ways. The former produced file with an .mts extension and the later produced .m2ts.modd & .m2ts.moff. When played with Windows Media Player, the properties indicated the same thing. It said the codec applied was AVC/H.264 for both. Am I getting two true AVCHD files? What is the real difference between MTS and M2TS?

What’s the difference between MTS and M2TS? Actually there is no functional difference between MTS and M2TS format. Both of them are High Definition files associated with the AVCHD video format.
