Several years ago, I had some old 8mm film converted to DVD by a company called Video Conversion Experts. They had very good reviews and the results were great. They offer 4 levels of processing depending on what results you want and the price paid. It's great to play the DVD occasionally; much easier than the old projector days. Might be worth checking out. They show samples of results.
