Has anyone else had this problem? This is the third DVD where I've had this message come up - I rip using DVDShrink, strip extras, compress a couple levels to fit, then use IMGTool to convert. This has worked great for me many times, but just the past 2 weeks I've gotten this error w/3 different versions of IMGTool (Classic 0.90B5, Classic 0.91 & 0.89). There is plenty of room on all my drives & I've tried each of them. Any ideas? Thanks!
