[linux-dvb] Flexcop (HD5000) dvr0 removes null pid?

Is this possible that when I use dvr0 of a flexcop card (Per example the
AirStar HD5000) that the driver/chip will supress null pids?

I modified a copy of dvbsnoop that verifies the PCR bitrate on a QAM, with
the AirStar HD5000, the PCR bitrate is lowered because the null pids are
stripped. I have not experienced this problem with any other card yet
(pchdtv hd3000, FUSION LITE/GOLD).

There is also nothing coming out of a null PID filter in dvbsnoop :
[root at dhcp-1172-8 ~]# ./dvbsnoop -s ts 8191
dvbsnoop V1.3.96 -- http://dvbsnoop.sourceforge.net/

root at dhcp-1172-8 ~]#

Output example of my PCR verification addition :
[root at dhcp-1172-8 ~]# ./dvbsnoop -s ts_rate -tsraw
dvbsnoop V1.3.96 -- http://dvbsnoop.sourceforge.net/
Trying to achieve PCR lock...

PCR LOCKED!

I have not looked in the source code of the driver yet, but will... I need
to be able to capture full Transport for further analysis, please help!

Thanks.
