This morning I connected my brand-new (not refurbished) 830. I got a 60 Hz slight hum from my TV set after I powered up the 830. I have never had that problem with anything I've connected to the TV. I guessed that it was a ground-loop problem so I plugged the TV into the same power bar as the 830. End of problem. Shaw Direct may wish to consider that if a customer calls in with that problem.
I expected drama, based on my previous refurb 630 problems. Nope, the activation went without drama.

I really like the new guide that provides show Season# and Episode#.
My only little quibble is the connection instructions that came in the box. It says not to press any buttons until the "blue light" goes off and the 830 restarts. It never happened; all it needed was a refresh.
As a side note, the problem with my now going-to-the-dump 630 was that only WGN acted as if it was not subscribed although I have always been subscribed. My 600 continued to receive WGN. I went thru hoops with Shaw Direct and finally most of the channels on the 630 disappeared. That's it! Warranty or not, I don't want to fool with another 630 refurb so I ordered the 830. Glad I did.
Another side note, the online MY ACCOUNT does
not show WGN as being subscribed. My wife told me NOT to call or CHAT Shaw about it. Don't fix what ain't broke.
