It is 10 days since your post below. I am very frustrated by the problem. I am paying $46 a month for whole house DVR which does not work as advertized. Customer service has credited my bill $20 a month, but I am still paying for a service I am not receiving and which was a big part of the reason I switched from DirecTV. Is there an update on this problem?
You may wanty to check signal levels between STBs.
here is how.
Log in to router
Click on My Network
As long as all of the nodes show at least 200 Mbps, you are good.
If you have some connections much below, then you may have a bad connection.
Make sure all of your connections are tight both on STB and at any splitters.
It affects all the set top boxes. The only time it is not an issue is when watching a recorded program on the dvr it is recorded on. Issues include picture and sound break up as well as the inability to fast forward (program resets to place where you started fast forward from).
I look forward to your insights and some resolution.
