Ripping a DVD that was recorded in VR format
I've made dozens of DVDs on a Phillips set-top DVD recorder, using DVD+R media. Now, I want to rip them (using Handbrake) so I can watch them on my Apple TV through iTunes. Problem is, Mac won't read the disk. Simply says "You've inserted a blank disk". Ignore or OK are my only choices. I believe the Phillips recorder used VR format. Yes, I finalized the discs when I made them. I also tried making a copy of the original DVD; that didn't help. The disks will play on my Pioneer set-top recorder, and one of my 2 Windows PCs. Problem with ripping them on the PC is that it takes about 3 times longer than on the Mac, and the resulting filesize is about twice as big. Obviously, I want to do this on my Mac! Mac has a Matshita DVD-R UJ-868 drive (factory installed). I would be SO grateful if anybody could help me. I've searched all over the web for help on this, to no avail.
