<font color='#000000'>LucasArts does not use the DTS-ES technology. THX-EX is based on the DD-EX platform, with extended, full range rears matrixed into the surround channel code. LucasArts feels that the additional disc space needed to encode an additional rear channel, in addition to the already higher bit DTS sampling rate requires too much disc space. As a result, picture quality suffers. LucasArts is committed to THX standards, and feels that DD-EX acceptably meets these standards. THX is not only about sound, however. Picture quality is also of paramount importance. Lucas also wants to add a director's commentary. Given the current limitations of the DVD medium, LucasArts does not feel that the addition of a DTS soudntrack or a DTS-ES soundtrack is worth the other, aforementioned tradeoffs.
These new discs will be mastered at the highest possible bitrate. Be assured that, with properly certified home theater equipment, the DD-EX soundtrack that LucasArts is currently working on will please you.</font>
