There are a few issues here.  As for the tools to cut, join, & merge Ogg
files, you'll want liboggz, which includes oggz-chop, oggz-join, &

As for the desynchronization issues with TS files, you may need a more
recent version of ffmpeg2theora, because, if I'm not mistaken, some
versions of ffmpeg were broken in relation to MPEG TS files.
