WinXP install problem - disc or drive?

[twentyINCHwheel]

I just built a new system, and have been having major problems getting WinXP installed and working. Here are the system specs:
Shuttle XPC SN25P
Athlon 64 3500+
Corsair TwinX1024-3200XL
Western Digital WD2500JD
ATI Radeon X800XL
NEC 16X Dual Layer DVD Burner (ND-3520A)

I put the system together correctly and it posted fine. I then proceeded to put in my WinXP disc to install it (if it matters, the disc is an original OEM copy that I bought around the time XP was originally released). The disc booted fine, formatted the HD, then went into the GUI part of the install... this is where the headaches begin...

At this point, the install was going slooooooooooooooow (even compared to installing XP on older Athlon XP boxes). I kept getting errors with WinXP telling me that certain files could not be loaded, and I let it proceed. Once it was done installing, I booted into XP, and I could not access my DVD burner, so I couldn't load up any drivers or system files needed to operate any onboard peripherals. No optical drive, no sound, no video drivers, no chipset drivers, no LAN...

At this point, I looked at my WinXP disc. Now I realize that it is about 4 years old, and it looks fairly scratched. I tried to clean it off with 100% isopropyl alcohol and cotton swabs, and gave installing XP another try. No luck - the disc still looked to be in bad shape.

At this point, I began to search around the web, and in these forums. Here are a couple of links that reflect almost exactly the same problem as mine:

Same problem: scratched XP install disc, same DVD burner, and installing to a SATA drive.

Any advice at this point?
