I spent ages looking at doing that but ended up just taking it to a local shop to do it for me. It cost about £15 ( I gave him double!) for a couple of videos and some 8mm and super 8 home movies. That was about ten years ago and the shop has since closed (unsurprisingly at those prices!).
There may still be folks who specialise in that sort of thing. He told me that my old 8 and super 8 films have a habit of self combusting, so I got rid of them once thay had been put on disc.
