I formatted my PC a few months ago and i'm sure i've not tried to write an audio cd since. Previous to the format though i have successfully written an audio cd. I can no longer do this. The DVD writer will write DVDs at any speed onto any discs but it will not write CD's. It get to the lead in stage and then spits its dummy out. I've tried writing with Nero 6 and Media Player on various makes of CD. I've looked for updated drivers and can find none although i have found a firmware update. What could be wrong and how can i solve it? Would i be ok installing the firmware or is there a chance of damaging the DVD altogether?
