hello all. Coming once again for help. I was wondering if there is some kind of free software download or plugin I could get that would decode DVDs in Dolby Prologic? What I want to do is watch older TV shows that were only recorded in Dolby Prologic on my computer of course. In my living room, my reciever automatically makes the 2 channel signal into surround sound, but when I play a 2 channel DVD on my computer, it only comes out as 2 channel. I have an Audigy 2 ZS sound card and I'm thinking it must have a simple ability to make a 2 channel mix into surround. I want real Pro Logic if possible, not just the 2 channels upmixed into 5 where all 5 speakers basically have the same sound. Thanks!
