Another test I did on a 30 minute recording (extracted 427 subs), the
following was logged

-> temp. file: 001.sp (1903586 bytes)
-> Subpicture PTS: first packet 04:25:56.729, last packet 04:57:02.643
-> adjusting subpicture at its own timeline
-> source is DVB Subtitle...
427 subpictures written...

I'm no expert on the in-and-outs of "PTS" timestamps, but the numbers
don't seem to be consistent across recordings.
Broadcaster / channel / dependent?
As you can see projectX moved them to a nominal position, sadly that
doesn't quite line up with the content, doubtless more to it.
