I beg to differ.. Nero CAN be a resource hog but this is easily remedied by not installing everything that comes with it..

I usually only install Nero Burning Rom, Nero Label Creator, and Nero Recode.. NOTHING else and it makes a noticable difference.. I also run msconfig after installing Nero and make sure nothing is set to start up automatically..

I find by doing that and only installing a fraction of the full software suite, nero uses very few resources and runs like a champ..
I definitely agree with you about Roxio though, Absolute garbage!..
