i am really into creating surround experience in movies....i know dolby headphone can do that...but looking in dolby website ,,there they say that DH create surround effect when multichannel audio is passed through it.
i have movies in 2 ch AAC format.i first upmixed them to 5 ch using dolby prologic 2 using ffdshow audio decoder(it has that mixer option).then i put that audio in DH...effect is good, but i am confused if thats really the perfect way to make DH works...i mean it is less surround and kind of lossy...

please someone tell me the perfect way to make DH works perfect with dolby prologic 2 and ffdshow....
