When I go to burn a cd in Nero 5.5, I can't set my burn speed any lower than 8x. I am using Memorex Music cd-r's, and they apparently aren't pleased with being burned at 8x, as they crackle badly on every cd player I try. However, they sound fine at 12x, it's just that most cd players don't want to read them at that speed. My burner is an Artec WRR-4848; I don't know what sets the burn speeds within Nero, if it is related to autodetecting something about the burner, but I checked for firmware updates and I have the newest version. This is all very frustrating, as I wanted to burn cd's as Christmas presents, and it is now February. It has been a struggle all the way, to say the least. I thank you in advance for any help you might offer.
