I bought a OEM Pioneer DVR-108 recently (ie, on wednesday) and it came today. i took out my lite-on cdrw drive which i believe was on a master channel (i also have a dvd-rom drive), and installed it in its place. when i booted up, windows did not recognise it and furthermore, did no longer recognise my dvd-rom. ive done some fiddling, and when i run the new hardware wizard thing, or add hardware in device manager, it recognises that its there and also recognises a "CD-ROM"drive (huh?). then it says the hardware has been installed and to resart my computer. ok, did that, still nothing there. it doesnt recognise either of my drives. i have tried the pioneer website but they provide no installation details and i dléd the firmware from the site and when run, it says there is no drvie. plz help me!
