--- Comment #6 from Sebastian Dröge (slomo) <slomo at coaxion.net> ---
I can't reproduce this with GIT master and also not with 1.14.1 (from Debian).
I tried with

gst-launch-1.0 -e mpegtsmux name=muxer prog-map=programs,sink_102=1 ! filesink
location=test.ts audiotestsrc wave=sine ! audio/x-raw,channels=2 ! avenc_ac3
bitrate=128 ! muxer.sink_102

And tsinfo on the resulting file gives

Reading from test.ts
Scanning 1000 TS packets

Packet 1 is PAT
Program list:
    Program 1 -> PID 0020 (32)

Packet 2 is PMT with PID 0020 (32)
  Program 1, version 0, PCR PID 0066 (102)
     Program info (12 bytes): 05 04 48 44 4d 56 88 04 0f ff fc fc
     Registration HDMV
     Descriptor tag 88 (136) (4 bytes): 0f ff fc fc
  Program streams:

Found 400 PAT packets and 200 PMT packets in 1000 TS packets
