I used Peterson's video services to transfer some 8mm, super 8mm and 8mm with sound on to dvds. Their prices per foot of film were lower than most other companies and about the same for the actual dvd charge.
I had them transfer my parents home movies that dated back to 1948 and continued until 1967 as well as my home movies that started in 1980. All I can say is this service is "priceless", I never would have been able to see the home movies from the my parents and never would have been able preserve them. Peterson's did a great job !!!!
