Making coasters. The disc will burn no problem. When I play it nothing happens. My dvd player says playback feature may not be available on this disk. When I go from dvd fab to nero 8 there is no problem. Burns perfectly. It happens when I need to use dvd shrink. My buddy uses the same programs and I have no problem playing his dvd's in my players. I'm using an LG External GE20 Super Muti dvd Rewriter with Memorex dvd r. Could I please get some help getting nero and dvd shrink to get along.
