Whenever I'm burning a DVD-R using RecordNow Max 4.5 and my Pioneer A05 burner, my computer lags terribly. What could be causing this? I have a TDK 40x12x48 CD-RW that has never lagged during burning. I have an athlon xp2600, 512MB DDR333 ram, asus a7v333 motherboard, 400 watt psu, geforce 4 ti4400... 60 gig hdd... I do have the dvd burner on my secondary slave right now... Should I switch it to Secondary master and move my tdk cdrw to secondary slave?
