I have the Kings Island 20th Anniversary TV Special that aired in 1992. It came off an old VHS tape and is in MKV format. The quality is not very good for an old VHS copy but watchable. The first few seconds are missing as well as the ending credits but everything else is there including commercials for Kings Island. There are some pictures of the video below.
I have added a downloadable version of the 20th anniversary video. It is about 650 MB in MKV format. You can use the VLC media player to watch it if needed. Happy viewing!
