Hi cawarra and welcome to cdfreaks,
The DirectShow viewer is still buggy for some users, but has been greatly improved with the last update.
It works just fine for me and many other users.
It also offeres fullscreen viewing.
First off, no reason to revert versions, assuming you don’t want to mess with DirectShow or you have persistent problems. Simply switch back to
[B]Internal[/B] rather than [B]DirectShow[/B] in [B]Common Settings > Preview[/B].
If you choose to use the DirectShow viewer, your best bet is to download ffdshow

DVDFab 22.214.171.124 Beta is out
Personally, I’m using ffdshow tryouts revision 1723 without any problems
