    Ok. A couple of other people besides me have seen a glitch with our ota tuner 2 caused by tuning to MPEG4 channels. Please run this test to duplicate this glitch we are seeing and post your results in the poll.

    Go to your HR20. Set both of your sat tuners to MPEG4 channels. For example turn to CNNHD and then go to TBSHD......or any other two MPEG4 channels of your choosing (dont use espnhd, espn2hd, tnthd, hbohd) but make sure to go to one right after the other so MPEG4 will be on both tuners.

    Go into your OTA signal strength meter and choose one of your OTA channels and wait up to an minute and see if your OTA tuner 2 (or possibly tuner 1) goes down to a 0 signal strength for a 1-2 seconds then back up. Once the glitch starts it will happen periodically. If it doesnt happen on that channel go up to another channel on the signal meter and wait. If not then go back to live tv and go thru the process again sometimes it takes a couple of times.

    Thanks

    I tried it again this morning. The signal varies a bit as you might expect, but no drops.

    Where is the OTA signal strength meter on the HR20's?
    All I see are satellite strength meters.

    An additional datapoint is that my unit, which has the problem, is an HR20-100 that was made in Mexico on 3/27/07. I know that some units were made elsewhere so perhaps this problem is isolated to those made in Mexico?

    It would be helpful if HR20-100 users would also indicate the country of manufacture and the build date.

    yah that could be a good point. also people. sometimes u have to be patient when going to the ota signal meter to see this glitch. and try two different channels on the meter. also...if u dont see the glitch the first time....go back to life tv tune to two mpeg4 channels again and then go back to ota and check again if u dont see the glitch the first time.

    my -100 was also made in mexico 04/07

    I have an HR20-100, and had a station that dropped on one tuner (tuner 1) from about 85% to about 50%. It is hard to get this to repeat, though. I tuned to other OTA channels without it recurring, and even tuning to the original OTA channel did not show the problem. Retuning one satellite tuner to an MPEG 2 channel and back also did not cause it to recur; only changing both satellite tuners to MPEG2 and back to MPEG4 channels caused the problem again. And the problem went away again with a change of the signal meter to a different OTA channel and back to the offending channel.

    so are u saying after tuning to two mpeg4 channels in a row then going into your signal meter and checking maybe 1 or 2 channels...waiting for a minute or two you have seen this same glitch?

    I see a similar glitch, but mine doesn't go to zero. I have to do a lot to clear things to get it to happen again.

    yah well...mine will occasionally do what you are decribing at first....maybe go down 20 points from 90-95 then down to 50 ....back up to 90's then it will start the zero thing. sometimes the zero thing happens for me within seconds.......other times i have to wait a while to see it happening.

    I had a similar, but different problem on one of my HR20-700's (0x18a). I was checking the OTA signal strengths, which looked ok. After I cleared the menu, I could not get any of the mpeg-4 channels to display (stayed on gray screen). Restarting the receiver corrected the problem.

    :confused:

    not really the problem we are talking about. we are referring to signal dropouts on ota stations after tuning to two mpeg4 stations. no mpeg4 channel viewing problems with this glitch

    I read (and understood) the original post. I would think any issue that is related to mpeg4/OTA signal strength problems on the HR20 would be relevant. Also, I did say it was a "different" problem. :rolleyes:

    ok, i understand your concern but your issue is completely different from the issue i'm referring to. no mpeg4 channel viewing problems here. this is related to glitches to ota watching/viewing caused by mpeg4. thanks for your input though.

    I did some more testing. I had my unit networked in anticipation of VOD, so I unplugged the ethernet cable and did a menu reboot. When the HR20-100 came back up, I tuned to two mpeg4 channels and went to the signal meter. The tuner 2 issue was there immediately. So, reboots aren't a temporary fix and the network connection does not appear to be a factor.

    Now that I think about it, I did not try a full power off (unplugging the power cord). I'll try that next.

    any word from any moderators that since about 30percent of the people responding to this poll are experiencing this problem.....if this is gonna be escalated and tested further? or is there just not enough response to do anything about this?
