Samsung R150 dvd can't be copied?

Hi folks,

This my first post, but I did a search before :slight_smile:

I bought a Samsung R150 a few months ago and successfully burned DVD-Rs directly of Final Cut Pro (Using Kona LHe, composite). When we were able to make copies of it, but now we can’t. The DVD will play fine on players, on Mac and PC, but neither will be able to copy it, neither over the hard drive or another DVD-R. Obviously, we try other brands media (Imation, Ritek, Taiyo Yuden, Maxell) but nothing to do. “Hope” someone got the same problem.

Thanks !
