Looks like there are TS packets in your stream that are marked as
"scrambled", but not unscrambled by the CAM.
Do you have any CAM in your system at all?
Are the channels where this happens scrambled?
Do these channels have separate VPID and PPID?
Does the problem go away if, instead of the above change, you
comment out the line
(Channel->Ppid() == Channel->Vpid() || AddPid(Channel->Ppid())) &&
in cReceiver::AddPids()?
