I purchased a Sony DVDirect to record old VHF tapes. Works fine! I tried to burn additional copy from the new disk but burner rejected. Lite-On DVDRW burner said "The target disc is either too small or not recordable." Target was not too small! DVDirect installation disc had "Nero 7 Essentials" which I decided to install as a possible solution. I installed and uninstalled twice before I realized I was going down the wrong road and did a final uninstall. Now the problem......I still have +/-13MB left and many registry items. Is there someway I can delete them or should I just ignore them?
