The current DTS parser gets the wrong order for DTS-HD frames and the 
associated Core frame. When the stream is a DTS-HD stream the core frame 
associated with an HD frame comes immediately after the HD frame in the 
stream (rather than before, which the existing code assumes). This code 
fixes that ordering and alters the decoder to cope with that ordering.

There seem to be a fair number of raw DTS-HD streams out there that are 
cropped to start at the first core frame, in that case this code will 
drop the initial core frame for HD streams as it should be regarded as
