Trying to burn an ISO file on Verbatim DL discs (the best media available). I am getting the following errors…“Write Protected”…using imgburn…I’ve tried multiple burning softwares, tried different types of DL discs, still the same error.

Searched through countless forums. Any help is appreciated. Thanks.
