i am pretty sure i know what i did, but have no idea how to fix it...i uninstalled Total Video Converter and when uninstalling, it asked if i wanted to uninstall some files and me not thinking just figured they were something worthless...

well to ake a short story shorter my DVD won't play anymore with any program i use

any idea how to fix this?

i already tried to reinstall total video converter and it still doesn't work!
