Ive been having problems burning cd's of mp3s. The other day (and this has happened before) the CD starts off fine but part way through the tracks have a realy annoying crackling sound. Then today i burnt a CD and when played in my CD played and the new one in the lounge it plays a second or two, then the next second or so are silent and so on. Any idea's whats causeing the problem? Its happened on Imation and Sony CDs (the only two bands ive used). Im using Nero 5. Ive tried buring at 4x (the slowest nero would let me go and im using an Acer 40x24x10 CD-RW. Any ideas what could be causeing the problem?
