I have been a DTV customer for 11 years and I am having an issue of which I am rather frustrated.
I had 2 HR20's, one 100 and one 700 and received my locals via off-air connected directly to the boxes. I then subscribed to the whole home dvr service. OK, I could watch 6-1 (Waco/Temple NBC) and it would be pristine, clear and sharp. However, anything recorded from this channel was either completely garbled, no matter which machine it was played from, or (very rarely) the recording would be viewable but it would constantly drop out/digitize out. This happened 9 times out of 10.
I called several times to complain about the recording issue and that the machines seem to respond in slow-motion when using the multi-room viewing. I was bumped up to the HR21-700's, two of them and the AM-21's for locals. I installed them myself. I am still miffed that after 11 years DTV WILL NOT give me the latest equipment, and that even one of the HR-21-700's sent to me was a refurbished unit. But more of the same and again, only with channel 6-1 (NBC). Again, about 90% of the time.
I called in again to complain. The tech on the phone noticed that I used my gigabit backbone (hard wired CAT 6 cables, gigabit router and gigabit switches) instead of the DECA units, so they insisted this was the problem. A tech was sent out, DECA's were installed, units were reset and I proceeded with normal TV recording and viewing. The tech that came out said that he felt the AM-21's were the culprit as the signal is sent to the DVR on the same "bandwidth" as many of the DTV channels and the DVR is getting interference. I disagreed as the signal itself coming in seems to be fine. But, now something new is happening with the DECA's installed and the gigabit ethernet disconnected: 6-1 when viewed is sharp and clear, but now anything recorded from it is clear and sharp, but ALL DVR functions do not work, such as rewind, fast-forward and commercial skip. When I try to use them, it freezes at the spot I am on for about 10 seconds or so then jumps back to the beginning of the program. If I just let it play, it plays without incident, but I am stuck watching commercials. I am really confused.
When just viewing the channel and nothing recording to the LIST, even the rewind live TV function seems to freak out. I can view for a couple of minutes, go to rewind and the units freeze for the customary few seconds, then jumps back to the spot in the program at the moment I tuned to channel 6-1. This happens probably 70% of the time I try it.
I called in to complain again, and this time, I was told that they were bumping it up to the software engineers and that an ETA for getting back to me could not be offered. I was hoping to throw this out to the "A-game" crowd and get some thoughts. Thanks!
Before anyone jumps on it, this is not a knock on 6-1 (NBC.) This is a recording/playback issue for 6-1, not the signal. Nor do I want to make this an issue of whether or not I should subscribe to locals through DTV or receive them free via off-air antenna. My reasons for receiving via off-air is that the signals are MUCH better quality, both video and audio and I DO NOT lose the signal for locals in bad weather. Most of our recording is via locals, so having them always on is vital, not to mention during the storms recently with all the tornadoes, I never lost any local channel signal and was able to get weather information.
