To Play Video Tapes Through Dhmi How Can I Play My 8mm Video Tapes Through My VCR?

How can I play my 8mm video tapes through my VCR? - to play video tapes through dhmi

I have some little "8" of videotapes 14 years ago that I can not play because the only way he could see was the actual video camera that is connected to the TV / VCR. Electronics stores tell me that do not fit my little video cassettes in the plastic "converter" box that can be used as a video cassette in full size. Is there something I can buy that fits my 8mm video tapes to watch my video player. My friend has a plastic box that fits in to see her little tape recorder in the video, but my films do not match. Thank you for your time.
