I have collected too many video files from VCD's on my machine. Recently i have purchased sony dvd writter. i got nero 7 cd alongwith that. but when i try to burn the video files on dvd, it is not accepting them. Dose those files require any type of coversion ? vcd files are DAT files... if it requires any conversion, which is that ? how do i convert those and burn them on dvd ? is any freeware available for the same ?
