    Here we go again... :)

    DO NOT ANSWER UNTIL L187 SPOOLS AND YOU HAVE A CHANCE TO TEST YOUR OTA FOR A COUPLE OF DAYS!

    Under L187, are you experiencing OTA problems? That is, do you have any OTA stations that you were previously able to save and tune to that you no longer can lock onto, save or tune? Do you have to re-add OTA channels after the nightly reboot?

    Once again, if particular stations are causing you problems, please report those stations in this thread, providing contact information for the stations if possible. At the very least, please provide the following information:
    • station call letters and city where station is located
    • the digital broadcast channel
    • the PSIP remapped channel
    • is the station broadcasting PSIP data
    • do your trick play (FF, REW, Slow motion, pause, etc) functions work with the channel
    • can you record successfully from the channel
    • do you get 0 second recordings from the channel
    • do timers set for the channel fire correctly

    The more information you can provide, the easier it will be for the programmers to fix the bugs in L188 or L189.

    Thanks once again for your participation in this data collection thread.

    I had to leave a quick new thread because the Submit New Thread is not working so I couldn't post it as a Poll. I don't know if Mark has not turned it on yet. I don't think I need to wait a couple of days for this bug because it has been going on since April.

    Severtiy:Minor

    I received L187 this afternoon and immediately pulled the plug on the 921 for about five minutes to clear any OTA database issues. I had removed all the OTA stations prior to the power plug reboot. I then scanned for DTV stations and still there is no local NBC station. The problem seems to have begun with L180. I've had the installer here to adjust the antenna and nothing could be done. I've had Dish send another 921 and it made no difference. It's down to either the software or something the local station is doing or not doing.

    I've tried calling technical support and they just refer you to your local installer/retailer so calling them does no good.

    Here is the local station information:

    I will move it to the "Post New Thread" section to add a Poll if Mark wants me to or if it gets moved to the "to be deleted" section.

    This is NOT a 921 problem. KOB will be back at full power later today. Try testing it this evening. See message below from Sean.

    I've had to manually re-add NBC every morning with L186 (or else suffer from the "Channel 5-1 Not Found" error when I try to tune it). I decided to try this again with L187, for the same channel (channel WMAQ-DT here in Chicago). However, in a bizarre twist, this wound up adding the analog version of the channel, so that when I later punched "005" into the remote, I was watching the analog station (which previously wasn't on my list of scanned channels at all, since I don't like to have the analog channels in the list).

    Steps to repeat:
    1) Go into the "Local Channels" menu and pick "Add DTV".
    2) Enter channel "29" and observe solid green lock with signal strength 110+.
    3) Pick "Save" to save the channel.
    4) On the channel screen, observe that the channel which now appears to have been added at the list is the analog one (i.e. analog 5), not the digital one (i.e. digital 29 mapped to 5.1)!

    Channel Information:
    WMAQ (Chicago) - NBC Channel 5.
    Analog: 5. Digital: Broadcast on 29, maps to 5-1.
    Previously was being lost every night on L186.

    My L187 problems:

    Still having issues with the local PBS station, KTCA in St. Paul, MN.
    Its signal on channel 34 is mapped down to 2-1. No subchannels that I can see.

    If I do a manual digital-channel add, is shows up in the channel list as an ANALOG channel (??), and I indeed get the analog channel 2 (regular VHF) if I tune to it from the program guide. So I can't even watch 2-1 anymore at all.

    In the L186, I could tune this channel in, watch it, and record it. The only problem was that the channel would vanish every night and I'd get the "can't find channel, go up or down" (or something like that) message. I'd manually add it and it would work fine for another 24 hours.

    In the one before L186, I could tune the channel, I could watch it, the channel didn't disappear, but always got zero-second recordings.

    Definitely a step backwards.....

    The CBS affiliate in Tulsa, KOTV, digtial channel 55 (6.1) still cannot use any DVR functionality to record, pause, skip back. Can only watch live.

    This is after 187 installed and power cord reboot.

    KCOP Los Angeles.
    Analog 13, Digital 66, maps to 66.1

    Scan locks the channel now (was not working previously), however, when I tune to it, all I get is a black screen. Have confirmed channel is up and I'm receiving very strong signal.

    KBHK (UPN, Digital 45, Analog 44, no PSIP) in San Francisco still goes black. No problems with KPIX (CBS, Digital 29, Analog 5, PSIP) which is owned by the same company and broadcast from same tower. After the nightly reboot I can select 45 from the guide and watch it, but if I change channels and go back to 45 then it is totally black until next reboot. There is no message that the signal can't be acquired. Signal strength 116 to 125 and says "acquired and locked". I can record manually after reboot, but still haven't been able to get a timer to record Enterprise in HD any Friday night yet. [​IMG] No 0 second recording and nothing new appears in DVR list. Trick play is fine. Nothing lost on reboot. I had previously phoned in this bug on L186.

    I have basically the same problem with this station. However, it DOES transmit PSIP, at least in some form. DonLandis was insightful enought to point out how to find out. Turn on closed captioning. KBHK has it, therefore, they are transmitting some PSIP info.

    For me, I can watch it once after a nightly reboot. I have been very happy though, because my weekly timer has been recording "Enterprise" regardless of the troubles I have had with that channel. This black screen problem was introduced in L186.

    The odd thing is that I haven't yet been able to figure out why the nightly reboot helps. I have found that a soft reboot doesn't help me get the channel back. I will try a power plug reboot soon. I suspect that there is some sort of a PSIP decode state machine, or an MPEG decode state machine that is not re-initializing itself. Very bizarre that we can watch the channel one time per day.....

    I am having the same problems as Redster with the NBC affiliate in Indianapolis (WTHR 13.1).

    All attempted recodings end up as 0 seconds. None of the DVR trick play functions work either.

    At some time in the past, all of the trick play functions and recordings worked fine on WTHR. I am not 100% sure, but I believe that the DVR problems with WTHR began when L184 was downloaded.

    The contact information for WTHR is supplied in Redster's post.

    Can the sensitivity of the 921 OTA receiver be adjusted from software? I have one channel that my 811 locks solidly on, but which the 921's lock is intermitent. There's an addtional 30 feet or so of coax to the 811, so it's probably getting a bit less signal to work with as well.

    Try disconnecting the 811 and the additional 30 feet or so of coax. That will give you around 4dB depending on the quality of the splitter. If it improves, then you get an idea of how much boost you need. What kind of signal strength does that channel show on the 921 when you manually add that channel?

    OK, here's my current summary of KNOWN problems with my 921 in Los Angeles. Please note that I have a strong signal for all LA channels, with a short, clear shot to Mt Wilson.

    One note from 186, I had reported that Ch 48 (KOCE 50-1,2,&3) would apparently add, but all I got was a black screen and no audio. Something apparently changed with the signal, because I started getting it perfectly before 187 downloaded.

    Problems remaining (and new) with L187.

    1. PBS (ch 59 remapped to 28-1 (HD), 28-2 (SD). Cannot record, pause, backup, or use any othe DVR functions on 28-1, the HD channel. This hasn't changed during the time I've had my 921.

    2. KCOP (the local UPN station). Can now lock and acquire a strong signal, and the station is added to the list as 66-1, and 66-2. This is an improvement. However, I'm not sure that there is a 66-2. In any event, there is no audio or video on either 66-1 or 66-2. And, I get the message "could not find 66-1 .... etc, and so on".

    3. KCAL (Channel 43, remaps as 9-1). This is a Viacom owned channel. I can add this channel and view it. However, the system forgets about it overnight, so I have to add it each day that I want to view it. Also, (and this is new with L187) when I add the DTV channel, it also adds the analog channel 9.

    4. NEW PROBLEM. (this could have happened before, but I never paid any attention to it, since I don't watch the channel). If I try to manually add (KDOC Ch 32 .. 32-1), the system says that it has a strong signal .. ~120 .. and it locks and acquires. But, after saving, it does not show up in the list of channels.

    My opinion is that L187 didn't do anything useful for me. KCOP appears to be "better", but I still cannot view it.
