Hi Brock ,
You might want edit your original game profile and change Automatic FES to FES ON just for the purpose of seeing the actual error sectors in the CCD log. Also make sure that FES correction method is set to Hardware as liteons chipset have a built in error correction mechanism. The Software error correction mode does not work well with Liteons.
Then when you are ready to read the image click on tools and open up the CCD log.
Most importantly, If you can post the Log in one of your experiments it would give us atleast something to look at and compare sectors and we might be able to pin point the problem.
As for trying the lower read speed, if your original CD is in perfect condition and your reader is quite reliable, which in this case is there should not be any need to reduce the read speed to 4X.
Reducing the speed often works when you have data corruption during the read, which often make the final CD not install properly by having data.cab errors.
