I've ripped 951 CDs with Audiograbber and only twice have I had difficulty. The first time was with the recent Foo Fighters double disc which I discussed in Foo Frustration. I managed to rip that sucker to MP3 thanks to software called AnyDVD and I wrote about that solution in Foo Solution.
Just last week I was stumped for the second time. Our Lady Peace's latest disc is a DualDisc and that spells trouble for rippers. Again, AnyDVD saved the day and I've got my music in the format I want them in so I can hear them where I want and how I want.
Take that, DualDisc!
