Thanks for the explanation, Thierry!
I now have tried to convert via ffmpeg. The command I used was
ffmpeg -vcodec copy -acodec copy z.ps.mp2 -i z.ts
This creates pack headers which don't seem to fit to the syntax
defined in table 2-33 of iso-13818-1:
00 00 01 ba 21 00 01 00 01 a1 9f 0d 00 00 01 bb
This looks strange to me. According to the syntax, the pack
header should be 14 bytes. Maybe I used the wrong options and
created a mpeg1 stream?
