When ever i burn anything, DVD movies for backing up or CD backing up it doesn't fully burn onto the CD. for instance i wanted to burn a CD using windows media player i watched it analyze it it went through each one just fine but when it burnt it only played up until the 6th song. the songs are not that long and the CD is not scratched. another example is when i was backupping 310 to yuma. i burned it and it was just fine up until the burning. i looked at the disc and it was clearly visible that it had only burned through half of the discs. what is going on? Is the burner just getting old?(i have backed up a ton of Cd's and DVDs by the way. Any help is welcome.
