Did you try watching the result?

Yes I did! Software player was MPC-BE (MediaPlayerClassic-BlackEdition)

As reported already, audio stayed in sync with video throughout the file's duration. On the 8 places where there were segments missing, you could instantly recognise a missing part but, other than that, the transition was "smooth" and required no user intervention...

Wouldn't your method only help if the errors were evenly distributed?
10% of the content would still be missing.

My "method" was just an experiment - I never claimed it to be a cure for the original issue - demuxing elementary streams from the --raw .ts file and muxing them back into MP4 (via ffmpeg or MP4Box) will just render an already downloaded file watchable, i.e. with A/V in sync, if the watcher actually doesn't mind a few (depends on file) missing segments...

Cheers, V.
