Extracting from several m2ts.

[jpsdr]

Hello.

When a movie on Blu-Ray is splitted on several files, is there a way, with eac3to or something else, to extract from the differents m2ts wich compose the movie, a one whole file of a track (audio, video or else).
Exemple : My movie is splitted on 00001.m2ts and 00002.m2ts, there is a dts audio track, and i want to extract the whole audio in one file (no re-encoding, of course).
Is it something possible.
If yes, how ?

Thanks.
