from main menu:
* Select Media->Manage Drives
* Select Jukebox to load from Jukeboxes list
* click Load Many button
* Cram 50 discs in
after which, I typically do an ID, to make sure that cover art will be gotten... check the results in the video list, and then go back to manage drives, to select Rip All.
There IS a visual bug where more than 6 discs will show up strange in the data grid. However, all discs will rip and/or play correctly.
