· The CD writing was successful, but it won’t play in my home or car stereo CD player!
Did you make sure to use a CD-R disc? Many people mistakenly use a CD-RW. Some newer audio CD players will support CD-RWs, but when in doubt use a CD-R!

· It won’t finish the burn or you end up with an unusable CD!
You may be having buffer-under run problem. The CD recorder must have a non-interruptible stream of audio data. If it is interrupted the burn will fail.

· Buffer Under-Run Problem
Buffer under-runs are a common problem with CD writers. A buffer under-run occurs when not enough data is streamed to the drive from the system. Buffer under-runs are very uncommon using CD Burner. The software has a very efficient multi-threaded buffering system. There are some things you can do to prevent this problem from happening by:
1) Disable other processes running as background tasks (virus scan, screen-saver, ect...)
2) Try using a lower write speed especially on slow systems.
3) Don't run other applications while recording (especially on a slow system).
4) Try not to access the hard disk - I/O resources are needed by the writer and CDR software.
5) Don't record from a network connection if at all possible - the network data transfer rate may be too slow.
6) Install more memory - this will prevent heavy hard-disc swapping during recording.
7) Disable auto-insert notification for the CDR.
8) Select the "Cache Image Before Writing" option on the Options window if you are burning Data CD or select "Cache/Decode files locally" if you are burning Audio CD
9) Try test burns before doing actual burns!
Doing any of these things will help you 'burn' more successfully and create less coasters. Most problems occur on slow systems with high write speeds (less data gets processed on time).
