I use nero vision and it does the job just fine. It always uses up 100% of my cpu but it's attempting to encode the file to dvd as fast as possible and hence it uses up all available cpu cycles. All encoding programs should do this.
If overheating is your issue than maybe a new fan would cool things down a bit more. What kind of temperatures do you reach?
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
