Seemed to work simply and flawlessly on my old Sony S590. Used a 32G USB stick (NTFS) with the Autoscript folder copied to it. Followed the simple instructions and the display just kept flashing LOADING. Went off to vacuum (retiree taking up housewife chores!) and returned to find the player off. Took the USB and plugged into my PC with Foobar (SACD component installed) and it opened the ISO up to display the MC tracks followed by the stereo tracks. Couldn't be easier. Thanks to all involved!
