well finally got it to work ...after days of googling and flaffing about....visiting other forums....with no help on here.
...poor show really considering all the experts and testers on here....thanks for nothing folks
if it helps anyone else out all well and good.
final thing that might have done it was I uninstalled my anit virus ....then did a clean install
....seems to have done the trick as I've finally got access to all my movie folders.
...if this mede8er ever gets problematic again its in the bin and i'll buy a dune or something
