I would agree with TimC, but if the disc plays under normal conditions then it would most likely be other issues.
It appears to be a system stability issue.
If your PC is overclocked, then undo the overclock and test at normal speed.
If your RAM timings are aggressive the try settings that are a little more relaxed.
Test your memory to ensure that it can perform under load.
Check your CPU temperature. If it's running hot then sometimes ripping can push it over the top and cause it to overheat and reboot the system.
Sometimes the optical drive is bad. If it's possible try another optical drive.
