Im using Memorex Cd R. Im down to 8. So they do work. I tried to burn a cd last night and it failed because they were wmv, not mp3's. So i decided to redo it and and find the mp3's for that album that i was burning. Now ever since then it won't accept my memorex cd's? My drive doesn't detect it. Ive tried 5 different cd's and it keeps ejecting it out. Is this my nero or is this my pc drive. How do i fix it?... i have been up all night trying to figure out this out this problem. I tried uninstalling my driver. Didn't work. I tried uninstalling nero. Didn't worked. I dont know what else to do. I did some searching in this forum. I came across this thread http://forums.afterdawn.com/thread_view.cfm/206497 this guy seemed to have the same problem except my nero was working and it was detecting blank cds for a while until last night. I skimmed through the thread and notice that you guys advised him to use the nero burning rom not nero express to burn the cd's. Whats the difference? My drive will not detect any kind of blank cd's...cd r/cd w. How do i fix this? Im currently using nero 7.
