I'm running Windows 2000 Pro on a DELL Dimension XPS T800r PIII 800mhz with 640MB RAM, whenever I use NERO to burn data or audio, it starts out fine, but after about 45 seconds the buffer drops down to 0% for a split second, then jumps back up, it might do that twice during a burn, I have DMA enabled and I also have a Pioneer 16X DVD Slot CD-ROM drive connected as SLAVE, but both drives have DMA enabled, but I keep getting these buffer drops intermittently thoughout the burn, CD's seem okay, but if I multitask, its seems to just be slow, almost like the burn is taking up too much of the CPU. Any ideas? The CPU should be fast enough for burning I would think. 640MB should be more than plenty? I also disabled my Norton 2003 anti-virus, doesn't help. Thanks!
