I tried and I think it is not missing CRC. The errors are in the 
CreateBlank() methods of ProgramMapTable and ProgramAssociationTable. 
They use the copy-ctor of PESPacket with a PesPacket created from a 
TSPAcket. If we use both constructors in this way 
_allocSize(pespacket:80) will be 192 (pkg._pesdata is set in line 38, 
pkg._fullbuffer in 53). But a TSPacket has only 188 bytes.
Not sure how to fix this, assuming that the constructors do in some 
cases the right thing.

The errors will probably not create any trouble.

I'll attach the valgrind error message to a ticket.
