1. cloning 3:10 to yuma, copy appeared successful, no error thrown. When I checked the Hard drive directory a 0 size file 3 (no extension) was there. I used "3:10 to yuma.iso" for the file name. please consider either precheck or post check of name format of iso file. This may be a bug. 2. After the first part of the clone process (creating DVD titles), I like to remove the original (while 'creating ISO/UDF image') and put in the next DVD to clone. After the first clone is finished, I hit the back arrow to get to the select drive screen. Suggestion: at this point, allow CloneDVD2 to see the disc has changed and rescan the disc for the new titles/etc. The current action runs a 'diagnosing/recovering dvd' routine. Greatest product on the market!
