eac3to was designed to convert E-AC3 and TrueHD audio tracks to AC3 or FLAC.

TrueHD conversion unfortunately doesn't work with demuxed TrueHD files at this point in time. The to-be-converted TrueHD track must the first (or better: only) audio track in an EVO file. Please use the EvoDemux tool to create one EVO file for a full movie with only the TrueHD audio track in it.
