Yes, DV is old
Yes, DV has had serious health issues
And... the person who films and "edits" his videos does a horrible job and makes it worse than it needs to be

I still have all of the DV books I've purchased in the last 20+ years and I've watched a good number of those vids, although some are extremely difficult to sit through. That's a shame, if only because DV is taking the time to present a lot of info and IMO the message doesn't always get through clearly.
