Issues

I have a Philips DVD8801 which as I have read is I guess a Benq DW1650. It was working great and then all of the sudden it will not recognize any discs. I read a lot of the forums about firmware, but I get a message that says you cannot update the drive. I have tried uninstalling and reinstalling. I can see the drive in my computer but no discs. Any help would be great. Oh, I have a Gateway GT5082 running XP. It has an AMD Athlon 64X2 Dual 3800+ 2.0 GHz, 2 GB RAM, 2 HD one with 32 GB for a PVR and one with 240 GB. Not sure if you need all of this, but just in case. Thanks.

Any ideas? Thanks.
