@FinGerZ - have you tested the disks that you've made? Try running Nero CD-DVD Speed and run a Transfer Rate test in those disks. Optimally the result would be a smooth curve from start to end, which means that the drive could read the disk at the mas physical speed at every area of the disk. If the curve is not smooth and there are deep down spikes, then maybe you should use a better quality media and/or lower the burn speed. Most computer DVD drives can handle bad burned disks better than the drives inside the DVD players, so that could be your situation. Improving the burn quality should fix that. i'll give that a try, i've used several spindles (100) of memorex 16x on my laptop burning dvd at 4x and this has just happened for the past couple of dvds
