as you may know, dear users, there are available plenty of video clips to download from the internet. yes, i have downloaded some and now i want to burn them as video cd. all clips ar mpeg. when i try to add them to video cd compilation in nero 6 or winoncd program says that there is required reencoding to mpeg format. why? clips are already in mpeg format!!! why do i have to reencode them? how do i avoid this problem?
