With avidemux you should be able to open the TS, and from there you can select parts you want to remove, etc. When you're done I suppose you'll want to save at as an MKV.
I've tried it. It does open the file, but when I press on play the audio and video are not synced, that's both with their "safe mode warning" or not.. Therefore when I try to edit the movie, I can't get a good glimpse of it.

Super is good, but not exactly needed for this
