"I get the same result with three different Fuji H471S Double Coated master
quality Super VHS tapes. What am I doing wrong?"
Sorry for this delayed reply.
Contrary to popular belief, S-VHS is not particularly immune to dropouts. I
frequently runs across batches of SVHS (professional grade) tape that simply
have too many dropouts. If you get a bad batch, return it for a different one.
