Comcast appointment #whoknows

I had another Comcast tech appointment today. See last weekend TiVo called me to work on the problem with the Comcast Cable card and the “flashing” that was occurring on about 25 channels. I talked with them for a while and then they conferenced in Comcast Phone support. The first thing out of Comcast’s “mouth” was “We need to have a tech come out and look at the lines in your house”. I was pissed, I spent the weekend before that with one of their tech’s who basically did absolutely nothing besides changes the ends in the house and replace the cable card. Neither of which fixed the “flashing” problems. So the phone guy, said he couldn’t do anything until a tech came out and did a in detail inspection of the lines. Haha what a freaking joke. So I had them schedule the appointment for 10AM today, preparing to waste the whole day on waiting for them to show up.

Like normal, 10AM came and past, around 11:15AM I get a call from a Comcast 866 number. It was one of their people calling to say that they ran out of cable cards in the area, and the warehouse was closed, and if I wanted it replaced I would have to schedule it during the week when the warehouse was open. I told them that I couldn’t and replacing it wasn’t going to fix the problem. I then explained what was going on and that the only real reason the tech was supposed to come out was to meter the equipment. She then said “Well the tech is running behind and won’t be there till after 12PM, is some one going to be there then?” I said I would and she hung up.

About 12:30 or so the Comcast guy showed up. Basically said “I know there is a problem with the cable card’s and I can’t fix it.” We then talked for a while about what the problem was and he said that there has been people calling in reporting it, but not one really took it seriously until Milan Puskar called in. It seems he had 15 TiVo’s at his place and ALL of them were doing the exact same thing as everyone else who had been calling in. That is when they finally started looking in to it. Go figure it takes a millionaire to get Comcast off of their ass to start looking in to the problem. The tech said that it is happening all over Morgantown and Fairmont from what he can tell, and every one is having the problems on the same channels.

He basically said there was nothing he could do except for pass it up to the supervisor for handling.

Here is a video I made of what it is doing. It is called “Flashing” by some of the Comcast phone people. I call it “Cable not working”. The funny thing when the tech left, was he said he hated working on cable cards because they don’t work. I was like hmm then make the channels unencrypted and you wouldn’t have this problem.

Since Comcast has not publicly admitted to what the problem is any place that I can find, here is something that I got from some one at comcast:

Only encrypted programs would be affected.  More specifically, only programs associated with segments that are part of more than twelve packages would be affected.  This is because the ECMs required to carry the entitlement IDs for up to twelve packages will fit into a single MPEG packet.  If more than twelve entitlement IDs are required, however, two MPEG packets are needed to fully encapsulate the ECMs. Not all two-packet ECM programs are affected by this problem.

The customer impact is further narrowed by the fact that only devices that specifically check the payload flag of the adaptation_control for ECM packets will be affected.  At present, and based on customer reports, this seems to be only TiVo devices.

Basically, there is an issue with decryption.  This will cause tiling, missing channels and not authorized errors.

  1. Every comcast tech has said to me they hate cable cards because they don’t work. What I don’t get is why the cable cards inside every one of there set top boxes have no problems, yet the ones they give us to use in TiVo’s have all these problems.

    Maybe they don’t work well because they don’t want them to work well.
