about ur 2nd problem, oftentimes when u get that problem it means that the cd's defective. although ur able to burn it successfully and ur pc was able to read the content, the thing is, it cannot be copied anymore from the cd to your harddrive. unless there's a way for u to fix the cd, which i think others have a way like putting some peanut butter on it or washing it, the files in ur cd cannot be retrieved.
