I am having the same problem with many of my back-ups now. Using a new version of DVD X Copy XPress, the burns will complete & play without a problem with Power DVD on my computer. When I play them on my stand alone player though, I am getting freezing & skipping. My player is the Sony DVP-NS325, which is supposed to play all DVD formats and has done this for me until now. In addition, with each different disc, the freezing & skipping occur at the same spot every time I play each individual disc. Why would the back-ups always play perfectly on my computer, but always freeze & skip at the same spots on my stand alone player? Is this a playback problem or a burning problem?
