I confirm that the solution works in practice for several set-top-boxes. 
Even disgusting hacks like setting PCR to (DTS-offset) give a perfect 
playback, provided the timing of sending of the data (over UDP) doesn't 
drift from this synthetic PCR (I wrote an external spacer for that).

That's nice, because sending padding packets over IP is against common 
sense ;-)
