Welp, you win the cookie for that one. Works like a charm here.
Honest, I tried asking google in many different ways first, but not in
the past 10 minutes since I found it was related to the AC adapter.
I'm still totally confused as to why the behavior "appeared" within
the past year, but meh.

I guess the upside of all this is that I now feel like I have a brand
new computer that can play HD video from my new digital camera and it
only cost me an afternoon of pulling hair.

Thanks Tom!
