Recently I found the need to access a old pressed DVD, it how ever has two rather minor scratches on it, these scratches are visiable directly form above, so they are clearly the problem when i can't access it. My theory is that if i heat the under side of the disk where the two scratches are gently, then hub them getly, the plastic should reset into it';s origional flat state, or at last flat enough for the DVD drive to read the intackt track. Does any one agree/disagrre or have any other ideas?
