ABC is currently not available on my livingroom TV, but comes on in the bedroom
Your DVR needs a stronger/cleaner signal than your DTA to work properly. The DVR also needs to be in a certain range to work properly, as it stands now, your DVR is not in that range. Other channels may not be coming in as well. Unrelated to X1, your modem also needs to be in a certain range to work properly, and it’s out of spec. You really should get a tech out to troubleshoot further. If you need assistance scheduling one, let us know.
