I've used MPEG Streamclip to do it.

As you've found out, you can't just join two arbitrary m2t files together. It's nothing to do with metadata. The files contain several timing fields and a sudden jump can cause problems or confuse software that attempts to read or play the joined file. Even if the software can handle these jumps, there is likely to be visual corruption at the joins where the inter-frame references are broken.

The best way to do this is to use software that remuxes/restreams the two files into one - effectively repackaging it without re-rendering the actual video and audio data, which I think is what MPEG Streamclip does.

Do it all the time with MultiAVCHD and it is free on top of that. The software is not real clear cut on the process but it does it and it is really fast in the joining.

Email me if you have any questions but I have posted the process here on the fourm somewhere.

I've just downloaded MultiAVCHD and tried joining .m2t files, but no success. For those who were successful, are you sure you're editing .m2t and not .mts? So far, I've not been able to join .m2t files with all of the above scenarios.

I have no .m2t files to experiment with, but this freeware app joins everything I've tried with it, including .mts files.

Here's my confirmed working method for this:

ffmpeg -i "concat:in1.m2ts|in2.m2ts|in3.m2ts|in4.m2ts" -c copy output.m2ts

That way you get a seamless result. Whereas if you don't merge with ffmpeg and just put the files on timeline in Adobe Premiere, there will be a huge gap both in audio and video. The above result is fast (no re-encoding). You have to naturally get free ffmpeg in order for that to work and you can concatenate as many files as you want (and .m2t will work fine).
