I have a asus p4b533-e Intel 2.4 with 2 Western digital drives in a raid (mirror) config, 1 GB of memory, Nvidia video, liteon CD-RW and matsuma (sp?) DVD. I just installed a liteon DVD +- RW and it won't work. It does not run and stops half way through the DVD burn. I tried everything. Making it the primary on the first id channel, making it secondary on the first id channel, making it Primary on the second id channel, making it secondary on the second id channel ... It just doesn't burn. I need help!!! OH I installed the same dvd in an ABIT computer with 550 mhz and 512 memory and it burns just fine. Any Ideas Any One ?
