I have two Gateway computers with CD/DVD RW drives. I using Xp Media Center SP2. I am using a trial version of Cyberlink DVD2Go. They both play cds and dvds. Neither will burn CDs or DVDs. I have applied that registry hack removing the upper/lower filters, no luck. I ordered and installed a new Sony cd/dvd unit and got the same results. I also installed the companion Nero software provided with the Sony drive and still no luck. I put the old one back in. I just recently found out about forceaspi and applied that, no luck. Gateway said I have to re-install ("restore") my system. I'd rather eat dirt. The BIOS recognizes the drive correctly, Device Manger reconizes it as the correct drive. "My Computer" reports it as a DVD R/W drive. If I put a CD RW in the drive and right click the drive it asks me if I want to erase the RW disk. I click it and it starts, gets maybe 3-4 bars and then hangs. Comes back and says erase has failed. Also, the drive is no longer recognized by "My Computer" or Device Manger. I have to reboot to "get it back." If I highlight a folder and right click it and select send to cd, it takes off 3-4 bars and times out saying the copy didn't work, BUT unlike erasing a disk, I don't loose the drive. Please tell me I don't have to re-install the OS!!
