S302M just happens to be a tricky one. Whilst s302m multiple substreams I haven't seen, Dolby E streams internally contain multiple programs, often 5.1 and a 2.0 downmix. Strictly speaking you have to handle the case where the Dolby E frame is misaligned and spans two S302M packets which does exist (and there is ambiguity about the PTS). There is a 3x3 matrix of flavours between coded Dolby E and the carriage PCM (16-bit, 20-bit, 24-bit).
