I thought from many older posts on this board that there were no advantages to using DTS over DD5.1 (assuming that both items came from the same master).

Since I have added a sixth speaker, I have had a lot of success with the 1050 using the 6.1 mode and abosolutely no dropouts. That includes all of the LOTR Extended Additions and numerous other movies that had problems.
