I'm with Charter and this is really just a complaint.
I think SDV is a great idea. More channels in less bandwidth. No need to broadcast channels no one is watching.
The Tuning Adapter is such a pain, though - at least with Charter.
When they first hooked it up they just kept swapping through tuning adapters across 2 days until they got one to work (about 10 of them).
Then they finally found one and, if it loses contact with the head-end it can take it a while to reconnect. I actually put it on it's on UPS just to try to prevent this.
Well, yesterday they were working on the cable and for some reason my TA got knocked out. I'm on day 2 now of trying to get the thing reconnected and get my channels back.
I have a service call setup for tomorrow morning (just adding to the pain) and I know what they're going to do: Swap out tuning adapters until one takes.
They won't look at, nor even seem to be concerned about, the fact that they go through 10 of them and only one connects so maybe, just maybe, there's something else in play here.. Nope... Just keep swapping them out until one takes.
It's incredibly frustrating.
If I could I'd just go DirecTV - too many trees in the way, though.
