I burnt a region free dvd on my sony DRU-500A It plays perfectly on my computer. WHen i put it into my nec dvd player though it plays perfectly for about 80 minutes then stops reading and starts skipping all over the place. WHen it skips though it is not displayed on the tv screen. It is like the dvd player is trying to find its place but it can't. Why does it play on powerdvd on the computer but does not play correctly on my dvd player. CAN ANYone help. I used GO TECH DVD-R media.
