ISO Cashing can be turned off in XBMP2.2.
You have to follow the instructions on how to get it all setup and working correctly first:
HereISO9660 doesnt work all that well unti XBMP2.1
(oops, edit: I meant 2.1 not 2.2. XBMP2.2 seems to be working much better)
What are the file sizes of the videos that are not playing back off DVDR?
I cannot get anything over a gig in size to playback at all...
I would like to get an idea of what the file size limitation is...
Thanks
