Hmm I will try all of this......
1st I will swap cdrom drives......Damn its such a good drive, I would hate if its bad. Its a Lite-on 16x DVD R/RW
I had a Samsung DVD/CD-RW combo drive that I was trying to install Half Life 2 off the 5 CDs. Everytime it got to a specific file on disc 3, it would give me a read error and crap out. Swapping in a Pioneer drive did the trick.
If you are getting the same exact read errors at the same point in installation using multiple install CDs, I would bet that there's a problem with the optical drive. Maybe the IDE controller on the motherboard doesn't like it, maybe it's just a faulty drive....dunno.
I'm not altogether on anyone's side, because no one is altogether on my side.
