Yep occasionally and its normal.
The tivo uses a separate internet connection which is quite low I think, and when you add the in the crappy internals of the tivo box......
I find it slow to enter netflix and browse but its fine when it streams something.
I mainly use my Amazon fire tv box which is speedy.
My TV app can't choose the user so as I am not the default user it goes to the wrong one, otherwise I'd use that.
If I have it plugged in VIA ethernet, should it be faster?
No I mean the Tivo box plugged in. You said Tivo uses it's own connection which is slow. So, if I have it plugged into my router directly, should Netflix be quicker?
Not sure thats possible. Im sure someone can confirm.
Personally I think its more down to the internals of the tivo box anyway.
Can you pause and rewind live TV on NowTV?
