I have compiled over a period of time all kinds of software and burnt it on DVD-RW. I have been happy using it when I had to do a clean install or for any other reason. Yesterday I wanted to reinstall my WinDVD software and to my surprise the Setup icon has changed to like a DOS command thingy. When I click on it a DOS window pops up and closes. I do not see any installer icons anymore in any of the backed up software. No clue what happened… is there any way to figure out what happened or any fix for it? I would hate to lose all my stuff….

that happened to me before..perhaps bad media? i read a warning in the back of tdk blank dvd-r stating that some medias can fog or damage the lens of the cd-rw/dvd-rw. don’t know how accurate that is but i dont want to take any chances. i have all my softwares on 3 locations.(tr/external hd/dvd-r).
