PESPacket is the base class, PSITable a subclass of it. HasCRC is
implemented in both. But sometimes we end up in the wrong
implementation because we put a SI table into an instance of PESPacket.

So the fix will be making sure that the right stuff goes to the right
pipe, but that's a bit more involved then just making the misleading
messages go away ;)
