I have tried everything to get this to work and am getting no where. A month or so ago I installed an I/O Magic IDVD16DL (http://www.iomagic.com/Products/show_all_results.asp?ProdID=IDVD16DL) and it worked fine for a while. After some time, it began writing at only .5x-.8x and would inevitably lead to a write error. This has happened three times now. The first fix I found was just to uninstall and reinstall the drive. Last time I flashed new firmware and it worked fine for a while. Neither seems to be working now, nor does anything else I can think of. It writes slowly regardless of the program that I use, too. I do not know what sparked the error the first couple of times, but this time seemed to begin after I used Windows Media Player to write a CD.
I'm running XP, with the drive connected to the secondary IDE as master with a slave drive, but I've also tried different configurations to no avail.
Please post if you need more information. Any help would be greatly appreciated.
