    One of the OTA tuners will not tune in my local ABC station, it works just fine on all other stations but when it is tuned back to ABC it is jumpy garbage pixels with no sound. When a show is scheduled to be recorded on ABC and another channel it reboots but 75% of the time lately and the other times just gave me a worthless recording. It is always the first OTA tuner, if that makes sense, I will be on 2 SAT channels and then tune to the ABC station then it will be junk. If I do it the other way around by changing that channel to another OTA then change the other tuner to the ABC station it works just fine.

    This issue has gotten more serious in the last week with several timeslots with reboots. The problem seems to be more prevalent after the 6.3e upgrade.

    I have tested with the OTA signal strength and this ABC station is the one with the lowest strength (50-65 on tuner 1, 40-50 on tuner 2 with dropouts). Tuner 2 will drop out on this station but on others it stays rock solid. NBC and CBS channels had both tuners steady in the 85-92 range with matching levels on each tuner. This is the weakest station but still, why would tuner 1 and tuner 2 have different levels only for this one station?

    Could this be a hardware issue? I have seen other posts saying something about an issue on the ABC feed, could that be related? How could this problem only affect 1 channel on 1 tuner, any ideas? Is there anyway to turn off one of these tuners to work around the issue?

    In my experience, you need signal in the 70's to provide reliable reception. Even then you may see an occasional breakup. My channels are all 84-96 and I still might see a brief breakup once a week or so, but get into the 50's and breakups are a regular occurence, as often as every minute or so. It would not be unexpected that signal in the 40's would be unwatchable or not lock at all.

    What you need is better reception. If you are more than 20 miles from the towers or have obstacles in between, start with a more-directional antenna, and make sure it is mounted outside and high. If you don't achieve better reception you will be chasing your tail trying to fix this. You can research almost everything you need right on this forum. At that point we can better help with targeted questions, which should contain details about your system.

    Thanks for the help. The problem turned out to be an equipment issue with the station itself on their digital feed. I am very close to the towers and my antenna is mounted off of the peak of the roof on the house so I wasn't thinking reception issues.

    I am still confused as to why 1 tuner is 10+ better than the other tuner and one is good enough to watch/record and the other is worthless. This makes it tough to let the Tivo do it's thing since we always have to be here when recording on that station to check that it is using only the good tuner...
