Many thanks Fengtao for all the hard work.
I have noticed that Platinum 22.214.171.124 has not correctly verified after the burn. Have only backed up two titles thus far, so not much experience with this. Previous versions seem to verify ok, although never had an error discovered. In both cases using Customize Mode, DL-9, Region 1, Verbatim DL, vso. The verify starts, but immediately reports that it is completeand ok, no time lapse; then the Finished box appears. Backup plays OK.
DVDFab has been flawless for me over hundreds of titles since v2.x
Any suggestions for a tool that can compare a finished disk to the HDD VIDEO_TS files? Wouldn’t mind a speedier method vs. DVDFabs verify. I guess one could use COMP from the command line, but clumsy.
