Ordered has long been the preferred dither option for QTR digital negs. I can remember trying Adaptive Hybrid long ago with OEM inks, but I don’t remember it being better than Ordered.
I think the answer to the second part of your question is contained within it. Think about it for a minute — if QTR supports Adaptive Hybrid (as it has from the beginning), why would the beta-driver be needed to support it? The dither algorithm you are thinking of is Hybrid EvenTone, which is not available in QTR, and has helped me with a few problematic images.
