I think it's difficult to do yourself, but this site tells
how they do it:
http://www.dcpproductions.com/8 mm film transfer.htm
8 mm Film cannot be transferred. It is converted. Using
state of the art digital equipment, re-shoot the film to
Digital Video (DV) film format. If it is a silent film
add Music. Then transfer it to VHS via high quality S
video if VHS is you choice and there is no editing to be
done (which is option 1 above). If not transfer the
Digital video film to digital editing equipment to add
effects, transitions etc and/or convert to CD or DVD
