From the release notes I see that the EAC3to tool uses the Cinemaster Video/ Audio Decoder for DTS Decoding. I messed around the registry keys for the Cinemaster Audio decoder and found that the following key controls the DTS Decoding Options:
HKEY_LOCAL_MACHINE\SOFTWARE\Sonic\CommonMPEGDecoders\4.2\AudioDecoder\DTSOuputOptions. The default for the DTSOuputOptions is 0xb hex.

eac3to is already manipulating these registry values to force the Sonic decoder to output all channels and *not* to downmix. eac3to's purpose is to deliver as many channels as possible. Downmixing to 2 channels is currently not supported. I could probably add that, but I'd need to know how this is usually done technically. Does anybody know? Which channels are mixed in with which volume?
