From the wiki ...
Go to Tools > Options > File types. Under "Data", click on "Disk Image Files" and at the bottom of the window, select your preferred Playback Method from the drop down list.
Problem being, I have no "Data" section in file types. I've got it on one machine ... but of course, it's the wrong one. I imagine it's some silly little switch I forgot to flip (or worse yet, flipped) that's screwing me up here.
Hep me!
EDIT >> Found it. OPTIONS/DATA/FEATURES, and check "Data Support". Not sure if that's set OFF by default or if I fat fingered it somewhere along the way.

Apparently this doesn't work with interactive DVDs? I was hoping to load up some music training DVDs to save having to do the shuffle when I get the urge ...
Did some more head scratching and decided JRiver isn't the tool for the job. Installed the following:

- Virtual Clone Drive (standalone, to mount the ISOs)
- VLC Media Player (to play the ISOs)
Working great.
