Thank you for your reply.
What I would like is this:
I want to use the UI so I can select the titles before ripping (I don't want sub-titles, alternate audio, or CC, for example)
therefore, when I insert a disc, I want nothing to happen
I click to scan the disc
those titles that are shorter than 30 seconds (rather than the 120 seconds now) are automatically skipped
I select which titles and audio tracks I want
I choose the destination folder if it's not already set
I click to rip the disc and store the selected titles into the destination folder
when done, the disc ejects automatically (this isn't happening now even with -e 'AUTO_DISC_RIPPER_EJECT'='1')
I suspect that these "AUTO" settings only apply if auto-ripping is enabled???
Perhaps auto-ripping with the minimum length skip plus automatic eject is the way to go...
