Flipper,
Have you tried installing the ASPI drivers as stated at:

Please try solution #2 to see if this will fix the problem. When you are burning a disc, the only drivers that it uses are the ASPI drivers. These are not used when it does the reading, so the read should work fine if these are giving you a problem.
Let me know what you find.
