Well...It works for me... I've just done it with the DTS 96/24 on Gentle Giant to fix the channel stuff up.
7.1.1 is the latest version available. It lists the content as dts 5.1 48k (doesn't list the bit depth).
AudioMuxer lists the content as 24/96 (as stated on the label).
Which version of DVD Audio Extractor are you running? Do I actually need an older version?
It really listed your content as 24/96 and let you convert it to 24/96 5.1 wav files? Not just 48k?
