FFdshow crashes DVD Fab and a question

Hi Everyone,

I tried using ffdshow for the previews , and it worked a few times than crashed DVD Fab . I’m running DVD Fab 5 Platinum mobile option on Win Xp Pro Sp3 . After, I deselected ffdshow for previews , I was successful in copying the main movie to my HD .
When I looked at the DVD full disc back up settings, for the same movie, I noticed the info page said that path player was disabled , even though I selected "always enable path player " in the path player settings .
Any ideas on what could be causing that ?
Thanks .
