Hey guys, I've have nero for a long time and never had this problem until i recently bought nero ultra like 5 months ago. It was working fine with burning up to 48x and then one day it just start burning at 4x even when check maximum speed, and i assure you it's not the cds since it is capable of burning at 48x and the dvd burner, or cd burner is capable of 48x too. The dvd burner/cd burner are new so it's not dying or anything of that. I try to see if the dma is set up right and yes it is, so i figure out it has to be nero, even if i reinstall it; it still give me the same problem. Atleast it works, but burning at 4x get on my nerve since i didn't spend money to just burn at 4x....Any solution would help out thanks.
Sorry I took so long to reply back, but yes i check everything from disc speed to disc drive and all set to 48x, even when i get to your screen shot i get 48x, but when burn it goes to 4x....
did you uninstall the ide controller link in devive manager and reboot pc? (this is an ide not and external drive?)
tried the actual drives too? and this isnt in the ide link in device manager. its separate above that link/line
