Excellent product! I use these discs in my JVC DR-MV100B dvd recorder which is CPRM compliant. Cannot record AMC (or other copyrighted broadcasts) without these discs or a DVD-RAM disc -- recorder will just display that it is copyrighted material and will not record on regular DVD-+R/RW discs. Will continue to use these DVD-RW CPRM discs until JVC stops making them.
