i thought that it would be both practable & ecconomical to purchase re writable cd's to save my video images on but they have proven to be very problematic in as they sometimes save ok and other times they dont, also when i try to play them back they take ages to load or they dont load at all i've tried both drives to play them on (dvd&cd)and the results are the same , but when i record the same images on to plain cd's they work perfect( except for a bit of minor noise distortion is this normal? )please can somebody help?
