Hi and congratulations!
First of all, you need Digital Link Manager For Lissa i uploaded it here (This is latest version 2.0) https://files.fm/u/apag6x3p
SonicStage not work with Lissa system - as i know.
But install properly Digital Link Manager is a chalange, I got it to work only on Windows XP - i tryed on Win7 but without luck.
There are also driver hell and how to attach them to lissa it work manually i have somewhere a tutorial how to do it.
and last, you need to wire iLink cables properly. iLink cable from STR-LSA1 To CD and from CD to MiniDisc then connect Firewire from other iLink port on STR-LSA1 to PC
Ok, i find my tutorial there it is: https://us.community.sony.com/s/question/0D50B00004PQidSSAT/sony-lissa-and-windows-xp-windows-7-avc-problem
And this is how it looks in PC -> MD recording (Nice that it transfers Artist names too) just press SYNC and it transfer automatic. Fortunately realtime.
