We've been noticing it for quite some time now. If it keeps getting worse, there's no need to keep the TV part of the cable, because TV that is unwatchable is the same as no TV at all.
And it's not just the TV reception - for some reason there's been this recurring problem with the DVRs where it responds VERY slowly to any remote command - like pressing pause and waiting 15-20 seconds - or longer - for it to get around to doing it.
Changing channels or bringing up the guide - and waiting as long as half a minute for it to respond.
Now we got an automated call saying TV would be down in the early morning for maintenance. Maybe that will clear it up.
