We had some good experience with doing this indirectly.
The fragments to be cut are ligated into concatamers (Fill-in if needed...).
The concatamers are then digested with your R.E. of choise, which now cuts
within the molecule with no problems. You should have enough fragments cut

Good luck, Benny.
