Hi spoonie3372 and welcome,
A few thoughts...
First off, you're still using Fab 4, this whole problem may be resolved with updating to current versions 18.104.22.168 Beta or the last final release version 22.214.171.124.
Try ripping the files to your hdd first, then convert the files. This frequently will work whereas the 1-step process does not.
Be certain to have selected always enable PathPlayer
If this fails, completely disable PP.
Do not select enable when necessary
Oh yeah, what are the titles?
