IIRC dual-layer DVDs are actually written into the DVD standard. If you have a DVD logo on the drive it must be capable of reading dual layers. Writing dual-layer DVD's is a different matter entirely, and reading burnt dual layer DVDs is hit or miss. But pressed DVDs typically don't have those problems. _______________________________________________ advisory-board mailing list advisory-board@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/advisory-board
