I have been on to Mesh five times today with the above problem. I have desktop running Vista Home and today both rewriters stopped working - they will play and show files but will not burn. I have tried two different softwares to try to do the job and they just freeze. Mesh say it must be a software problem and want me to use their Software support at £1 per minute which I think is a bit much. If I format and reinstall will this solve the problem and if so how do I go about this with Windows Vista and a recovery disc or would it be possible to restore to Factory settings. All advice appreciated.
