Just for an update to my problem I emailed Fab Support and they said...
"I am sorry to say that we are working on this problem, and we will fix that in the near future. Thanks in advance for your patience.
Any questions in the future, please feel free to contact us."
On another note I was having this problem with the movie Green Zone. I ripped movie only to the Hard Drive with DTS HD Audio. Tried to play it with WMP and it wouldn't play. I demuxed the HD audio out of the movie and remuxed it with AC3 5.1 audio. I tried to play it with WMP and I got sound with blank video. I then re-loaded the movie only file back into Fab and had Fab shrink it down to 8 Gig movie only. I tried to play it with WMP and it plays fine now. That's just weird!!!!
