I just had X1 installed in my home and after 4 days, I returned my equipment. It was a horror show. I was about to sell my extra Tivo units, but decided to cancel that.
Let's start with the installation. As soon as the installer arrived, he said the following: I'm in a hurry and these installations take a long time. He connects everything in about 40-50 minutes and stated you're all set. I tried a few channels and the only channels that I could receive were the local channels. He said this is normal and give it 2 hours. 3 hours later, still only local channels.
I then call the dedicated X1 support number and explained the situation to the support person. She then resends signals to the receivers (2 DVRs, 2 standard x1 satellite receivers). After being on the phone with this person for 90 minutes, one of the DVRs still does not receive all of my subscribed channels. One of the satellite receivers still cannot see its host DVR. She tells me that she has to escalate to tier 2 support and I should expect a call in 72 hours. Needless to say I am extremely ticked off (using polite language here).
The next morning, I turn on the one DVR that is working and there is no sound. I have to power cycle the unit and the sound returns, but all recordings are lost. As for the non-responsive satellite unit, I press the reset command on one of the setup menus and it begins to work. I call Comcast back to ask them to refresh the signal on the other DVR. Once they do that, it begins to work. DVR #2 loses it sound the next morning so I had to power cycle that one and again lost all scheduled recordings on that device.
Now that everything is "working", I decide to play a few things through On Demand. The programs stated they were in Dolby Digital 5.1, but the sound was horrible. I had the proper sound setting to ensure I received it 5.1, but it sounded like I was listening via a tin can. My receiver states that it is in 5.1, but there was no distinction between the speakers.
Finally, let's fast forward to today. I ran errands earlier so I had set the DVR to record a football game. Prior to leaving I had set it to add one hour to the recording time. When I return, I watch the game in FF to catch up. At the end of 3 hours, the recording freezes. The box is non-responsive for 10 minutes. Needless to say, it did not add the 1 extra hour. That was the final straw.
Fortunately, I live close to a Comcast office, so I returned my equipment. After a usual Saturday afternoon wait, I spoke to the rep and told her that I wanted to return this. She asked me what was wrong and I explained all of the above. She said, our installers don't know what the hell they are doing when installing this. She said, it's really great equipment. I told her that this has put a bad taste in my mouth and I'd rather just use my Tivo equipment.
So, if X1 is in your area, run away and stick with your Tivo.
