DVD Fab HD Wont Recognise HD DVD

Hi guys,

i have just put in a HD DVD drive into my HTPC. HD DVDs play fine with Power DVD, I can explore the HD DVD in windows explorer, I can rip the HD DVD using Any DVD trial version but DVDFab HD wont recognise the disc ( Last Samurai).
It is fine with DVDs though.
Any ideas?
thanks in advance.

I know this might sound a bit silly, and I sure don’t want to be insulting, but are you sure the dropdown quality selection on the opening screen is set to HD DVD?
