SATA DVD Burner and Biostar MB Issues

Hello, I have a question that I hope someone can help me with.
I recently purchased a LITE-ON 20X DVD±R DVD Burner With 12X DVD-RAM Write SATA Model LH-20A1S to replace an older outdated HP 300i burner. I have a Biostar MB model NF325-A7 754 NVIDIA nForce3 250 ATX, with an AMD Athlon 64 3200+ Venice 2.2GHz Socket 754 59W Single-Core Processor. 768 SDRAM DDR400. Any way. I purchased the SATA Burner drive as I know that SATA has a faster transfer than IDIE. I have built several computers in the past with no problems. After installing the new drive, my computer sees it as a DVD drive, when looking at "my computer" but when I go to install the drivers and software that came with it. Nothing happens. "My Computer" changes it's mind to a CD ROM drive. Wierd huh? It won't open the contents of the disc. Infact it doesn't even recognize a disc is in it. I have updated my MB with the latest BIOS and still nothing. Am I right in assuming the drive is bad? Or do I have a SATA issue between the MB and the DVD Drive?
Please help. Thanks
