You know what, maybe the quality of the CD is ok.. but the quality of 
the burner is not. There was a roundup review of DVD-RW a while back in 
Anandtech. The first thing I notice is that one DVD-RW produces more 
errors on the same blank DVD than others. Cheaper DVD-RW usually gives 
out more error, some cannot even read the DVD it burns.
