Blu-Ray TrueHD tracks contain both AC3 and TrueHD packets.
Those packets don't have anything to do with each other.
A standard AC3 decoder can decode the AC3 packets, but not
the TrueHD packets. A standard TrueHD decoder can decode the
TrueHD packets but not the AC3 packets.

HD DVD TrueHD tracks do not contain any AC3 packets.
