Can't extract non-copyright VOB files from DVD-R on my MacBook Pro
I'm using the MBP Retina (10.8.2) with a SuperDrive. I am able to see and extract VOB files from other non-copyright DVD-Rs and DVD+Rs, but these ones, which I made myself on a Panasonic DMR-ES40V VHS-to-DVD Recorder, are not even showing up in Finder. That is, I can't even see the VIDEO_TS folder when I click on the disc under Devices. I should mention that these discs do play just fine on my MBP's DVD Player application. Their file structures are just invisible. Any suggestions on how to get at those VOBs.
MacBook Pro with Retina display, OS X Mountain Lion (10.8.2)
