Hello, I'm using a trial version of the latest Nero and although it burns movies okay when I come to play them on either of my 2 DVD players I get the message 'can't play this type of disc.' Nor will they play in the computer - it either freezes or doesn't read the discs. Now I'm using DVD+RW discs and what I can't understand is that the numerous very same discs made previously with Nero will play on both my DVD players perfectly. The only difference is that I'm now using a new computer with Vista rather than Windows XP with which I made my previous discs and I'm using a trial version of Nero., although this shouldn't make any difference as they burn okay, Other than those differences everything is the same. All the files are in MPEG. Other than it being Vista rather than XP operating system I can't see why my previously made discs will play and the ones I'm trying to make now won't. One other thing is that bit won't burn at all using the longer play facility. Is this just because it's the trial version? Anybody help please?
