AVCHD video cut (trim) without re-rendering

As so often with new equipment also appeared with my new video camera Sony CX 106 days after the first few hiccups on already. Here also the right solution.
Problem: Filmt oneself, it seems inevitable that all the videos start with the fact that you yourself directly in front of Kamarea is (because you have because you just pressed the record button) and then only for its intended position occupies the end, then vice versa: One approaches the camera to stop recording by pressing a key. It would be nice here, a remote control that is missing but for most affordable cameras. So you have to remove the first and last seconds of a video then.
In the first attempt I've tried this, the cutting function of the camera itself. You can actually share on the camera shots. For this purpose you choose the recording controls to the desired location and then cuts. The parts can then be trimmed to remove the camera. When I tried to then copy the cropped video to the hard disk of my notebook, I noted that the associated video file itself (ie the *. mts file) was cut, but apparently only a playlist for this video was altered. With the included Sony software could be cut but then this copy to disk (as new, slightly shorter *. m2ts file). Strangely, this file from the Media Player from Windows 7 was played perfectly, but with the VLC player was not exactly in sync sound and image (the sound was 0.5 seconds too late). When you load this file up on Youtube, I had to find that were also not snychron picture and sound.
So I tried it with other methods to cut the file. Of course you can accomplish with a full-blown video-editing software like Adobe Premiere, but I was never there a way to change like this video as a new file to store the entire video without re-rendered - and therefore erneit compressed - is. I was sure that it still had to be any freeware tools, but the result of the Google search was quite thin. Apparently it is more difficult to edit a AVCHD file as such an AVI file, for which he gives numerous tools.
However, I found a few tools of which TSremux and tsMuxer the most promising impacts. This I found no setting to really frame the split point with accuracy, instead, leaving only the position set in whole seconds. Watch out the way: In TSremux are the positions of front and rear expected given in seconds. So if you need minutes, for example, from a video of the length of 2:20 to cut the first two and last three seconds, one must not start 0:02 and end points indicate 2:17, but the starting point and end point 12:02 00:03!
Problems with trimming TSremux
Unfortunately was the so-cut video image and sound out of sync with it.
Ultimately, it did work then but with the Sony software (PMB). The ability to cut is not really something, so I initially did not find (trim to manipulate / video). This allows the split points specify frame accurate. The resulting file is both the VLC player as well as YouTube plays fine. I suspect that if the solutions do not cut frame accurate, sound and pictures are not cut exactly the same.
Ultimately had to cut the video with the Sony software PMB
