well, I do not think cinelerra can just pass original audio untouched (
May be this can be coded, but IMO Cin's main focus was on re-processing
input audio and video, not just cutting. Also, input sources for one
session can vary... {this one is less of problem, just so far there is no
'guess' table that can be used for setting up parameters from already-known
at encoding time session params}. Maybe encoding profiles can be used for
this, need to look..

I was thinking about integrating tsMuxer but this does not solve problem
about unavailability of pre-encoded packets in cin's vframe for mpeg2..
Probably BC_COMPRESSED  type should be split for mjpeg/dv/mpeg2/h264 types
but this is larger rework than I can attempt from tablet ...

May be for cuts-only you can export edl and then use ffmpeg's copy/mux mode
? (no ready to use script for this, sorry)
