When Using DVD to Mobile Generic H264 + Mp3 setting (that I had used successfully before upgrading to DVDfab188.8.131.52) I get the following
Task_1 Failed! Error=7(534 3)
Process Completed Successfully
it only takes a couple seconds to get this error and no file is even created.
I have tried it now on multiple DVDs and ISOs with the same result. I have even launched the old version of DvDfab but got the same results.
