Apparently David Del Valle (and Barbara Steele) produced '96's Dark Shadows 30th Anniversary Tribute. However, I checked the reference books for the '91 Series and his name doesn't appear as associated with it, so I suppose he was only offering opinions without actually working on the series...
Many will be happy to see who his favorite character of the original series was...
