Please can someone help ? I am using Toshiba Satellite 350 I have made a film in Windows Movie Maker but I am unable to burn the disc . I click on 'burn in Windows DVD maker and as soon as it gets to about 34% an error message comes up '' Unable to create DVD unspecified error '' This is the third film I have made, the others were fine . I have tried two different types of blank DVD's . Thanks Update I have just tried again and I now get the message ''Cannot create DVD catastrophic failure''
