This patch should fix this.

Would the log messages look like this without above patch?

Those were the reports I got from users.

Patch for remux.c doesn't fix the problem if i use my Hauppauge
PVR-cards 500 !

With DVB-T-/DVB-C-/DVB-S-cards/-channels everything works fine.

Can you please provide a 1 minute VDR recording from that device (made
with the most recent
developer version that works for you) and tell me where to download it?

The upload to Sigi's FTP-Server has finished.

The filename is problemvdr1720pvr3sat00001.ts !

Apparently in this file every TS packet that starts a new PES packet
has the "Payload Unit Start Indicator" flag set. Normally (AFAIK) this
should only be set for TS packets that contain the beginning of an
actual payload unit (which may consist of several PES packets).

So I would assume that the TS data is in error.

I would say this is the expected behaviour as one PES packet normally is one payload unit. The MPEG2 standard only defines that when the PUSI bit is set a PES packet shall start in the payload of the TS packet. There is no other limitation.
