You should not have this much of a delay when changing the channel. I would recommend a couple of steps to see if we can help improve the delay. First, when you have a chance, can you check the connections to ensure they are all secured and the cables are undamaged? Next, if you are using a splitter, can you bypass it by connecting the Coaxial cable directly from the outlet to the cable box? Then if you are using an amplifier in the home, can you check that its cables are secured and the light is lit to the AC adapter? Finally, I would try power cycling the cable box by unplugging the power for 30 seconds and then reconnecting it. Please let us know the results.
I have the same problem and have tried all the suggestions that apply to me, nothing helps. I exchanged the contour box a while ago for the same reason and I don't want to do that again because I lose everything I've recorded. It really seems like a problem with Cox.
This has been happening to us for a while now and I'm really sick of it. Sometimes when watching something on the DVR, it just decides to start the show over. Then if I try to fast forward to the point I was at before it restarted, it won't stop until the end. The DVR has been a big problem for a while now and I'm wondering if it's worth it.
If it's slow changing channels it could indicate an issue with the levels going to the box. How many cable outlets do you have in the home, and if you have more than you are using, you need to verify they are not connected. Unnecessary splitters reduce levels and could have something to do with the issue you are having. If not, then you may want to replace your splitters and cables that you can get to, to ensure you have good connections all around. If that's doesn't help, then a service call may be in order.
