I have been using AnyDVD and CloneDVD2 for some time now, mostly compressing a backup onto 4.7GB discs and have had reliable playback. Recently I have been backing up with +DL (8.5GB) but have found long delays occuring at the layer break when played on my stand alone DVD player. Whether it is significant, I am uncertain, but if a title is 6GB or less in length it more evident than titles closer to 8GB. I have also experienced some freezing when played back, both on my PC drive and stand alone player. Not sure if the two are connected. Any help appreciated.
