* Support little endian streams on Big endian output. In theory at least, the Mendelssohn_2.wav sample never worked for me. I think the dtssys demuxer has an endianness issue (probably in the header code or something). In my opinion the dtssys demux should only output big endian streams, because all DTS is generally big endian. It's just that .wav often isn't.
