I recently bought a new computer. A recorder was already built in it ad it came with the Nero burning rom software. Now when ever I try to record a cd-r the following problem occurs : the cd-r seems to contain all the data or audio I burned on it, but when I try to play it on a standalone audiocd-player, only the first 6 or seven tracks work. When I skip to the next track, the cd stops and is being ejected. What could be the problem? Oh yeah, when I look at the burned side of the cd-r media, only have of it is burned and in the middle I can see a broad line burned all around. Please help me. Greetings Peter
