I have the TM700 and can get the mts files through Windows explorer with the camera connected via USB or I can use the HD Writer software and it imports them as .m2ts. Vegas edits them both and I can’t see a quality difference, but there is some kind of difference between the two, at least with the TM700 files, as the HD Writer and player will only see the .m2ts files. Even if I change the .mts extension to m2ts, the HD Writer software won’t see or play them.
The only reason I would use the HD Writer software is, it’ll play back the m2ts files very smoothly, but Media Player classic, Power DVD, spash will play the mts files just as smoothly.
