Apparently, now eac3to starts a second pass to write a 16 bit track in case it was only 16 effectively. So if you always use -down16 on thd tracks, you will lose the least significant 8 bit of audio data in case of a "real" 24 bit track.
However, if this is an audible loss of audio quality is highly questionable. I only use 16 bit for all formats.

ok i understand this stuff now.
i dont use the switch -down16 for other convertions. only in this case.
with the v3.22 create eac3to a 24bit firstpass file and then the secondpass file with 16bit, which works fine. the original truhd.file is defintiv 16bit.
