My suggestion is strictly for troubleshooting. Try Videosynch to see if it works. While the trial version is time limited, its function is not. So IF you can make it work in Videosynch, I’m not suggesting you buy Videosynch. IF you can get it to work, then you have eliminated a variable and you can come back to banging on DVDFab knowing it is DVDFab. At this point you don’t know if its the software or something else. D/L one of IMTOO/Xilsoft’s products and try one of them. Same reason. Eliminate a variable by seeing if it works in another package.
I don’t care for Videosynch either. I use TMPG DVD authoring but even with that Videosynch’s interface is just odd looking.
Yes you will need DVDFab to rip the DVD. But that is all. So encode it with different package. After ripping with DVDFab can you use a DVD software, PowerDVD etc., to play the files on the hard drive and do the hdd files have sound? If they have synched sound then your having a problem with encoding. Encode with something different.
If the hdd fiiles have problems with sound, the problem is in the ripping.
Right now you have too many variables to nail the thing down. While you may not fix the matter with a package like Videosynch, by eliminating variables you get much closer each step to finding the fix.
And yes it is time consuming and frustrating.
