Of course this means basic things I used to do easily are no longer doable.
Previously, I could have the clock on the box turn off when the box was offer, and have the channel # show on the box when I am tuning. Now, I can either have the display off all the time whether the box is on or off, or I can have the clock on or off but now show the channel when I tune, or have the channel show when I tune but only if I want to have the clock on all the time.
And then there's the VCR timer. It used to be I could go to one place, tell the box to turn on to channel 28 at a particular time and record a program once, daily, weekly, etc., and then turn off. Now, I have to set a Power On timer to start programming, but then have to go to a separate place if I want to set a Power Off timer. So it will take me twice as long to set up my recordings. Of course it will be much simpler if I'm renting their own DVR...
When I decide I want to complain, I notice that the nice brochure they sent out doesn't include any contact info for Time Warner cable other than their website. Some companies might at least set us a firstname.lastname@example.org e-mail address or something, which maybe they'd never check but at least would give you the impression they care, but Time Warner's Navigator is now so perfect that it couldn't possibly be that anyone might want to communicate with them about it in a good or bad way.
And of course when I dig out the phone # to complain to someone who confirms that I can't do the same simple things I could do a week ago with my cable box, he has no name and address to give me of somebody I can complain to. Now, this irritates me no end, when customer service people in publicly traded companies that all have web sites where you can find out the name of the head honcho and find out the corporate HQ address decide you really should have to go treasure hunting on the internet for this information.
