During the first pass through my DVD collection with Mac The Ripper and Handbrake, I found countless titles that couldn't be ripped for one reason or another. I just put them to one side and carried on with the rest. Having seen advice on here about external burners, I decided to buy a Pioneer drive and just mount it in the second optical bay on my Mac Pro. The different has been staggering, both in terms of speed of ripping and the way it has sped through the previously problematic discs. Just wanted to post this in case anyone was considering the same and wanted to know how well it worked.
