Hi there all, i did a quick search on google and you guys came up with a lot of problems simular to mine. I have the LG "HL-DT-ST DVD-RAM GSA-H55N" burner. it has been working fine for ages. I installed a new master drive at the weekend and now the little bugger will only burn DVDs and not CDRs. I did have this problem for about a month before my new drives and was unable to fix it then too. It's odd, it will burn the DVD just fine, but not CDRs. I;ve tired 3 different brands too. My computer is fast enough so there is no worries there. I am currently updating NERO7 to see if that makes any difference. Is there a known problem or fix for this? Thanks for your help.
