More compatible?

I got used to using this model of blank dvd a long time but now it seems I encounter a compatibility problem with my living room recorder of the same brand.
The device actually does not recognize the support and refuses to format the while well formatted the same older media and I recycle.
I'm a little disappointed and circumspect, especially since I have two other devices of the same brand and who themselves format the new media.
I am therefore satisfied with the product but compatibility!
