My 4 year old son somehow managed to purchase some minion episodes for $10 or so. How do i go about blocking any purchases?

how to use remote to delete library recordings

Have a new Samsung UN58TU700D smart TV.  I had to download the Direct TV Stream app.  It appeared to install properly. I have a 60 Mb Ethernet connection to my tv.   Problem: The resolution goes from fuzzy to basically ok, but never what I would call HD or sharp.  I've had to install a FireStick to get an acceptable picture.  It mostly happens while watching baseball on AT&T SportsNet. I, of course, would prefer to skip the FireStick and watch TV through my Directv Stream app.  I can't find an option to show me or adjust the video connection resolution. I'm very disappointed - seems like the processor in the TV would be better than a $29 Firestick! Thanks for any suggestions.

The website management page says my receive is not connected to the Internet. I've checked the receiver itself and it shows that it's connected. I can also stream demand content.  I want to connect so I can refresh my receiver. I'm hoping this will fix my issue which is that when I select "channels I get" it still displays all channels. My receiver is an HR24-500.
