I've recently purchased a Samsung DVD writer to backup my photos, music and movie collection.
When backing up movies, I use DVD Decrypter and DVD Shrink to do the back-up which is then perfectly playable on the Samsung DVD unit but not on the NEC DV 5700A unit originally installed. It does play some DVD -R's but not if I'm backing up my movies. The disc is not recognised, rhe same happens on my actual DVD player.
Does anyone know what could be causing this?
