Simitar's 5.1 Surround Sound?

[Monsterzero 1965]

One thing about the Simitar discs that interested me since I became interested in sound design, were their 5.1 surround sound mixes. While they mostly consist of added sound effects in the rear channels, I'm still interested in listening to them. So does anyone know where I can listen to the sound mixes?

I would assume only on the DVDs themselves. That would be the only way to have the actual experience of that specific mix.
