I'm using the last version of DVDshrink in a Windows 7 VM (Parallels) under OSX 10.7 (Lion).
No problems except one: VM has limited Disk space and I have to rip about 30 DVDs. I don't have so much space on VM and I'm using the MAC disk. Under windows I can see the Mac disk in two ways:
1) as network disk with UNC path (like \\psf\Ext-2\DVD)
2) as mapped drive under windows (like Z:\DVD)
In the first case (UNC path) DVDshrink is working as expected, saving the ISO correctly.
In the second case (Z:\DVD) the program save 6 files, 4 file of 1 Gb (.I00 to .I03) plus 1 file to fit DVD size .I04 and 1 file of 5Kb .MDS.
I think that there is something wrong..
