Odd DVD2one error: it's confusing a mounted dvd for a real one

[NicklePickers]

Hi,

I'm a longtime user of the simple method MTR (full iso) to DVD2One to Disk Utility for backing up DVDs. I recently ran into a problem for the first time with DVD2one. When scanning the mounted ISO produced by MTR, it says that it cannot read directly from DVDs and that the file needs to be copied to the harddrive first. The thing is, the file is already on the HD. I've never had this problem before. (The current DVD is my copy of The Trip to Italy, in case that's relevant.) Any ideas?

Thanks,

Nickle

Hast mtr been updated? You might have rip with something else.

I'm on 4.1.5.2. I rarely do updates because I rarely have reason to since this version tends to work great (and still works great) every time but this one. I did update the DVD2one (from 2.4.1 to 2.4.2) but it didn't change anything.

I've never ripped with something else. Do you have a recommendation? I could also do movie only, but the error made me curious.
