Hi.
Norm is sending me the diskettes with the latest program and software loaded for the 568 so I can install it on my laptop which I haven't connected to the internet. So I'll install the latest software which comes with the newest 568's. I really don't know if I have any Dolby Prologic 2.0 discs that aren't also DD5.1
For DSS, I'll see how it compares to the Super preset I use!
