How about setting up a filter for PCR? I mean, in test_dvr.c there are set 
up two filters, one for audio (DMX_PES_AUDIO) and one for video 
(DMX_PES_VIDEO). There is, however, a constant named DMX_PES_PCR. Can that 
be used to get the PCR with the stream?

Apparently n-tv sends PCR as a separate PID and not inside the video PID? 
Do you know the PID to be used? Video PID is 162 and audio is 96, at least 
with them I have got some kind of TS out of the /dev/ost/dvr.

Strange thing is that every 12th (or so) TS packet is coming with the 
adaptation field set, but there is no information in the adaptation field, 
no flag is set. Why is that?
