Don't bother switching to the DEV slice, we already know it's not a problem generally with everyone. So there must be something specific different about your hardware that is triggering the problem.
One thing it may be worth doing is switching to exFAT. That is one thing that is different between your HDD and others, again just trying to ascertain what is effecting the error...
It's interesting that it requires the data to be playing back... Is that just on the local drive? What if you play back video from a file server or something? (or a locally connected flash drive)
