I just recently got this nec 3520A and am having a problem. I am using dvd shrink and dvd decrypter to burn the movies at 8x. I am using fujifilm 8X DVD +R made in Japan and the media code is YUDEN000-T02-00. They burn no problem, but when I go to watch them about half way through it stops/stutters and either skips back to a previous point in the movie or skips ahead a few minutes. This has happened on the first two movies I have copied. The dvd player I am using is Sony DVP-NS400D. I tried it in a different player and it worked fine. Is there some kind of setting change I can make or firmware upgrade (it is just the stock firmware now) that will allow me to burn compatible dvd's with this media for my Sony DVP-NS400D? Thanks for any help.
