our Netgear router and told it to cough up a list of attached
devices, showing the same list of stuff that the first two sweeps
found. Additionally, there was 1 mac address with no other
information such as an IP address or system name, just that MAC
on a row all by itself.
I had been looking for our DVD player which has the
ability to view streamed movies and I think this might be it.

will take that MAC and let you know which manufacturer has that
block assigned.
My question is, did the link she went to on the computer
or maybe her iPhone use javascript to get our WiFi password and
if so, how did the player get the authorization to use our WiFi?
1. It found an open wifi network
2. It's plugged into your ethernet
3. Your wife gave it the wifi password
I am just curious about how did this work and could a
person cause it to log on to our WiFi network and receive a video
stored on a system here?
Quite possibly. The systems for this is called several names, but
the most likely are UPNP, DLNA, ChromeCast or AirPlay.
What I am actually thinking of is more like a DVR where a
computer can record a TV show like the old-school VCR's and then
one could play it back through the DVD player on the network.
Suitable Debian packages include:
mythtv
vdr
kodi
and for music, many others.
This player can also update it's firmware when necessary
and we've never been prompted from it for a WiFi password. It
just seems to be able to get through when it needs to.
That's suggestive of already knowing your wifi password or being
on a wired network.
