To owners of Dolby Pro Logic amplifiers: help needed!

Alas, I used to have a set up to do this, and I still have it, but unfortunately I've converted my set up to be music only and have thus changed the surround speakers into being cabinet speakers that are simply a little smaller than the front speakers, then moved them to be on the wall above the front speakers (giving literal meaning to the term, "Wall of Sound" hehe)

I don't know if this will help you or not, but do you have the video editing program "Womble"?  Because if you do, you can drag your 2.0 DPL2 track onto your timeline and export it, and under your export options if you select a 5.1 ac3 as your output file it will do a PLII upmix for you and then your file will be like it would have been if played on the right hardware.

If you like I'd be willing to do that for you.

Yes but you see the problem with my setup is that it's not set up as surround, it's set up as just massive stereo.  (the surround speakers are set up ABOVE the front speakers, as opposed to being spread behind the listener, because I only use this setup for music these days)

Well send it to me and I'll let you know! :P

I've been busy and haven't had time to listen to the examples, but in my experience there isn't really anything out there that's better than Dolby Prologic II.  To me it strikes the ideal balance between channel separation and overall sound field stability.  Other processes either have too much crosstalk between channels, or sacrifice stability and let sounds move around between speakers too much when they shouldn't, which sounds strange and can create distortion in some cases.

I've never been able to detect any difference between the results of hardware decoding as opposed to software.  Jim Fosgate's original design was an entirely analog process, but Dolby has only ever released Prologic II in digital form, for after licensing the design they analyzed it via computer and came up with an exacting digital representation of the circuit behavior.  Hardware decoder chips and software program versions are running the exact same algorithm, and will therefore come up with identical results.

As the name indicates, Movie mode is ideal for playback of most film soundtracks, especially those that are Dolby Surround encoded.  The dialog is concentrated in the center channel, and the surround effects are sufficiently diverted to the rear speakers to provide a convincing representation of their intended placement.  Music mode is ideal for any 2-channel soundtrack, music or film, that is in regular stereo does not have Dolby Surround encoding, since it focuses centrally-panned sounds less into the center speaker and uses the left and right to a greater extent, and uses the surrounds more for low level ambience than for panning purposes as in Movie mode.

You mom has been busy taking care of all of us.
