Every time I burn a CD using Nero (or anything else) on my Windows XP machine, the entire system locks up for like 5 seconds. It happens when the burner starts making noise. Then when it comes back, it starts burning and does a great job of it. What is this lag and how can I stop it?
Is the DVD burner on its own IDE channel or is it daisychained off the primary HDD? (if you're using PATA HDDs, that is)
If it's freezing and your HDD and burner are on separate channels (best practice) and DMA mode is enabled, then it still sounds either like an IRQ problem or your machine doesn't have enough free resources to buffer the burn session in RAM (how much RAM do you have? Do you have On-The-Fly burning enabled?)
