I installed dish and the hopper 3 three days ago. I think I've found Netflix to me network related, but more on that after I do more testing. I played with setting and sniffed my network packets for 5 hours and I hope imresolved the Netflix issue.
As for YouTube, well it broke again. It gets stuck until the box does a reset, confirmed with reset logs in diagnostics. They need a way for us to hard kill the app by holding down a button on the remote before the app forces the Hopper 3 to soft restart. This interrupts recording and stuff.
The first time I got YouTube to work was going from Ethernet to wireless. After I thought I fixed it I went back to Ethernet and it broke the next day. Netflixmis still working, but at least when netfixmdid fail it gabe an error and didn't crash the box. I bet it has kernel panic logs also from these crashes along with memory dumps.
I tried the reset YouTube settings, now I can't stream from the iPad with the YouTube app so I know it did reset the setting but still just a black screen. Also went back to wireless, still broke, and unplugged and logged back in, still broke.
So even as a YouTube content provider I was looking for ward to YouTube on the big TV without having to change to another device like PS3, or using the smart part of my TV that isn't that powerful or that smart. I don't think I've used the smart part since the first week I bought it. I have onemofmthe first smart TV's from Samsung that doesn't have the processor or memory module upgrade option.
Oh well, I give up on YouTube in any device unless it's a tablet, phone or computer from now on.
