No our DVD player is not hooked to anything-it's old-school (gosh I love old-school!) 

But this morning when I got up I had no internet (funny that) so I called and after working on it a bit and getting it back on, I then addressed the data drain issue. 
She made sure I was saying it was not my drain and eventually gave me 1GB back (out of the 1.7GB I lost) so that's good enough. 
All I can say is I will be paying closer attention to being 110% sure everything is totally off every night and screen capturing before I go to bed, and monitoring during the day-including that old antiquated hourly usage meter. For what we all pay, I'm not going to ignore those kinds of drains...
Thanks everyone...
