There was a movie from the early to mid 80's set in mid evil times. I believe it was a HBO production. About a young man on a quest or maybe revenge for his slain family... The only highlight of the movie that I remember is he had a magic bow that shot arrows really fast. What is the title and can it be found on VHS or DVD?

Hawk the Slayer (1981)? http://www.imdb.com/title/tt0080846/

Or maybe the TV movie The Archer: Fugitive from the Empire.
