AppleTV 2 & 3 as 5.1 Surround Sound DTS Player???

Has anyone figured out a fix to get the 2nd and 3rd generation to play DTS 5.1 Surround Sound audio files?  It works perfectly on the AppleTV 1:

Someone told me it has to do with the 2nd & 3rd generations insistence on outputting audio files in 48MHz.  Is there an easy fix to get them to convert and play at 44.1MHz?
