I have an HP Pavillion 8770c with a Mitsumi 4804 TE cd burner.Win 98se. I downloaded Nero and Roxio easy cd creator 5 Platinum. I converted my files with TMPGenc. When I tried to burn a VCD I destroyed my discs. They now show 0 bytes available and 0 bytes used. What causes this problem? How can I fix this problem?
