Incomplete burns

Hi there, I’ve been trying to burn audio cd’s with my new computer, but no matter what i do the last 3 or 4 songs dont burn properly. I’ve used nero express and windows media player. Both say the cd was completed successfully, but the songs at the end either pop and skip really badly or dont play at all. I think my burner is an LG GCE 8520B (52x24x52). Anyone know what I’m doing wrong?

What i would first would be to check for the quality of the source files (badly encoded mp3 files, scratched cdrom), use different/better quality media and/or write @ lower speeds and/or using another software for the burn ie EAC.

Then i would search for a new firmware for my drive, new chipset/bus drivers, check aspi etc.
