Comment (by peter_b):

 '''Stream analyzer:'''
 Used ffprobe (show_frames/show_packets), but didn't really know what to
 look for.

 Wanted to try "[http://dvbsnoop.sourceforge.net/ dvbsnoop]", but the
 documentation I could find seems to already require too much in-depth
 knowledge of DVB-streams in order to make any sense of how to use it.

 Tried "-async 1", but the commercial A/V of the commercial is out of sync
 until "he's a captain!" (ca. 1m55s). That behavior is as close as I get
 with ffmpeg.

 Sorry to post it as bugreport, but if MPV is able to make sense of the
 stream, I guess it means that ffmpeg can somehow be able too. Especially
 since ffmpeg libs are the base of MPV.

 Thank you very much for looking into this!
 These A/V async issues are quite common with MPEG-TS recordings, and it
 would be great to use ffmpeg to fix them :)
