I have TME 1.0.6.31 trial installed. I just tried to convert a dts file I found here:
http://www.kellyindustries.com/sounds.html
Specifically the file named dts_the_other_side_48khz.dts , its about half way down the page in the DTS 48Khz section.
I have "C:\Program Files\Arcsoft\TotalMedia Extreme" in the PATH environmental variables in system properties.
eac3to v2.63
command line: eac3to dts_the_other_side_48khz.dts test.ac3
------------------------------------------------------------------------------
DTS, 5.1 channels, 0:02:36, 24 bits, 1536kbps, 48khz
Decoding with ArcSoft DTS Decoder...
Encoding AC3 <640kbps> with libAften...
Removing DTS zero padding...
Creating file "test.ac3"...
eac3to processing took 10 seconds.
Done.
