media player wont burn

hi, when i try to burn a cd from media player i get the message "Windows
Media Player encountered a problem while burning the file to the disc. For
additional assistance, click Web Help." There is nothing wrong with the cds
and have tried diffrent brands. Thinks its definetly something wrong with the
media player or maybe a problem with the drive used to write the cds. The
drive is the one that was included in the pc mwhen bought. Any ideas PLEASE.
loads of music but cant burn anything!!! Any help would be much appreciated.
Thanks.
