Dear Sirs: I have had no problems with CloneBD output until today. (Using version 18.104.22.168). I was attempting to copy Stargate - 15th Anniversary Edition Blu-Ray disc, but the two attempts I have made have both resulted in 27GB unplayable files. Please note that there were no error notifications while the copying was ongoing. Furthermore, there are CBDLog files that appear after the copying completes. I have not seen this behavior before (auto-creation of the log files}, so I assume they are indications that the copying process had severe problems. I would like to look into the files to see what the issue(s) are, but have no idea how to do so. Would you please post instructions on how I can open these log files? I will upload the two files created, but I would like to know what went wrong with the copy process. Thank you for your assistance.
