Blu-Ray TrueHD pids should always contain both. At least that's
what the specification requires.

In my own software, I've a parser/splitter which understands
both AC3 and TrueHD. It looks at the raw combined TrueHD+AC3
bitstream and splits it into two separate streams.

However, somebody (Ian?) mentioned earlier that the Blu-Ray
TrueHD stream consists of PES packets with two different IDs.
I was not aware of that. If that's true, splitting could be realized
simply by looking at the PES IDs...
