Another update on the video playback issue. I uninstalled whatever update I was pushed for YouTube and tried to play back a random video. It failed. I disabled HD playback, and it started playing. Tried another one with HD off and got the same result. Reinstalled the update and and got the same result again. Appears it's an issue with HD streaming/playback, but that may just be me. Can't test with downloaded videos as I don't have any.
Can't get the netflix app to connect far enough for me to sign in and test. Going to futz with that for a bit and update in the morning.
Edit - tried with no luck to get Netflix working. Just keeps spinning, and from what I can tell, isn't pulling any data at all.
