Thank you. I was totally lost but wouldn't you know it? Once I did connect using content manager the message for copying the game changed to use content manager!
WHY ? Why do I keep getting a message "Could not connect to the PS3 system?"
Ah, I needed to sign into the joint account on the PS3. Now I get a screen on the PS3 which says "Connected to the Playstation Vita System." I cannot copy by going to the game screen. The vita provides the protocol menu!
Now maybe I can actually use my vita.
In case anyone wants to know. The following steps are sufficient:
Sign into PSN on both the PS3 & Vita
Uncheck charge via USB in the system settings
Have the PS3 idle other than being signed into PSN
Bring up the home screen on the Vita and scroll to the Content Manager button
Connect the Vita to the PS3 by USB
The Content Manager throbs. Tab Content Manager and a menu comes up.
In case of a cannot connect message, gnash teeth and retry.
