Hi Fred.
I checked again, yes you are right.
PSR tries to search for the same title on another memory stick. If he doesn't find it, he shows ! sign.
I have had several memory sticks in use, and then there have been confusions with the stick change.
I don't want to check right now, but I think Restart with C6 key deletes the Playlist. I just now had it empty and at some point I was forced to do a C6 Restart. I think it's safer to keep your stories in Registri Bank.
With respect,
Innar.
