I'm hoping someone can help me out. Our RNS-E only seems to like genuine discs and we've been on 2005 for ages. I recently bought genuine 2007 DVD's. The updated software installed but now it won't recognise DVD1 but works with DVD2. So what I need is try another genuine 2007 DVD1 so I can establish if the one I've bought is faulty. If anyone can help me out I would really appreciate it.
