I have dumoed Nero cuz the probs i had and have got my hands on a Roxio easy cd creator disk, (version 5).
IT COPIES CD'S!!!! unlike that Nero *!@:e.
Problem is tho is when Roxio is burning a CD the computer becomes un-usable and when task manager is opened (eventually) it shows that the process Cd Copier is using alot of memory and the the computer usage at the bottom of the screen is at 100%.
i have never used roxio so i cannot really help that much but can you give us some more information please?
what version of the software are you using and what version of windows do you have? may help a bit. roxio support site click here
try this in the meantime:
if you have windows xp click 'start/control panel/system/hardware/device manager' then look for 'IDE/ATA/ATAPI controllers' click the + next to it and then right click the 'primary' and 'secondary' IDE channel, select 'properties/advanced settings' for each one and set the 'transfer mode' to 'DMA if available'
try updating roxio to version 5.3.5 if your version 5 is lower than this. update and instructions on how to check your version can be found click here may help.
ps. for the record i only have a humble 1.8 P4 with 512mb of ram and is rare to see my cpu usage going over 20% when burning discs and i can happily carry on with other things at the same time so 100% is not normal at all in my opinion.
whats the cpu usage like when its just sitting idle on the desktop? have you run a check for viruses and spyware and have you run disc cleanup and run a defrag lately?
if all else fails try updating your motherboard chipset drivers maybe.
