What brand of disc are you burning to and what speed? It could be poor media or
as it has already been said you might have a bad pressed disc that may play fine
when playing it but causing you problems when it is ripped and burned.
I suggest you try some different media to burn to and see what happens and if it still
does it on different/better media than you most definitely have a bad pressed disc so
take it back and get it exchanged for another one.
