Hi, I am looking for an analog-digital converter to use with home movies from 10-12 years ago from an analog camcorder. I am deciding between the advc-55 and the advc-100. I have read that both of them are excellent with good source material. However, I am worried that with my older movies, that there will be a noticable difference in quality in the transference to digital. Can anyone comment on the difference between these two in this respect? Or any other that you think is important (as I may use this for the long-run for other types of projects)? Thanks so much.
