I just did a conversion to WAV. The process took exactly the same time: 15 minutes, 5 seconds. So, it appears that it's the decoding process that is damn slow. I will try to uninstall the ArcSoft decoder, to see if the default DTS decoder (which one is it?) is faster...
eac3to just uses the functions that the decoder/encoder libraries provide (dtsdecoder.dll, libaften, libav, etc.). If these are not multi-threaded, the process won't be multi-threaded. The default DTS decoder is libav and it is a lot faster than Arcsoft's.
Encoding to AC3 with libaften should be multi-threaded (I think).
