Can it be read in your writer?
If it can be read there, it is the combination of your recordable and your DVD player.
Are you using a CD-R or a CD-RW. Some DVD players can not handle CD-RW...
When you made sure you did not select 'test only' (if that is an option in CDRWin...not sure, long time since I last used that) and the CD-R(W) is not readable in your writer as well, there might be something wrong with the program (which is kind of strange when it gives no message of failed writing process).
