Thanks again for your reponse Tim.
The media boxes (xmp etc) are currently unchecked. Again, i’d read elsewhere from Adobe support that this is a good thing to uncheck in these circumstances. Do you agree?
Audio mapping is ‘use file’ and the p2 media has 4 x mono channels (one of which is empty).
re: the drive, always comes up with same drive letter, never have a problem seeing the media when the proj is opened. under write priveleges for the drive, all is ‘allowed’, owner is my as a vista user i log in to prevent any administrator blocks.
Sehd any light?
