I can't say there's any difference in picture quality at all although there is a problem with DV black clipping at the moment (clips at 85). VS10 options are good but confusing and overly complicated. There are a few other niggles but the biggest problem is the interface and movie management - Zidoo beats it hands down in my opinion. The Dune interface is awful - honestly it's just terrible! Back in the day it was only ever really viable if you completely reskined it and used yaDis for movie management. Problem is yaDis was abandoned years ago and just doesn't cut the mustard these days and the new GUI can't be skinned. The old GUI is still available though, which is somewhat of a saving grace.
Cheers. Yes back in the day I used yaDis on my Dunes. My Collection was always pants. TBH looking at the video review it seemed that they had improved it quite a bit. Hoping for a Zidoo firmware drop very soon!?
