Unable to Create Graph When Watching and Recording at Same Time / HDHR3 (2 Viewers)

I keep receiving the error, "unable to create graph," whenever I try to record a channel while playing a channel at the same time. When I originally installed MP, I remember being able to record and play. Not exactly sure what I did or changed, but I'm tinkering, and I don't seem to be going anywhere.

I'm using an HDHomePrime HDHR3-CC. I uploaded the tvservice.log. Not sure what else might help. "scheduler: no free cards found for recording." I'm guessing that's the issue, but I don't know how to fix it.

Any help would be greatly appreciated :).

    Hello and welcome :)

    I keep receiving the error, "unable to create graph," whenever I try to record a channel while playing a channel at the same time.
    Recording 1 channel while viewing another at the same time should only require 2 tuners. You have a PRIME with 3 tuners so in theory this shouldn't be a problem.

    In practice, what I see in the log file is that only 1 tuner is usable.

    When TV Server tries to use the 2nd tuner (with ID = 6) I see messages like this:
    [2015-09-19 03:23:30,899] [Log ] [scheduler thread] [ERROR] - Exception :TvLibrary.TvExceptionGraphBuildingFailed: DRI CC: tuner appears to be in use
    at TvLibrary.Implementations.Dri.TunerDri.BuildGraph()
    at TvLibrary.Implementations.Dri.TunerDri.BeforeTune(IChannel channel)
    at TvLibrary.Implementations.DVB.TvCardATSC.Tune(Int32 subChannelId, IChannel channel)
    In other words, TV Server is detecting that tuner is being used by some other software or "external agent" (TV via DLNA/UPnP etc.). TV Server will refuse to take control of the tuner because taking control might interrupt recordings etc.

    As for the 3rd tuner (ID = 10): from what I can see, you've configured TV Server to avoid using it (because all your channels are only mapped to the first and second tuners).


    Questions
    1. Is it possible/likely that the second tuner is in use by "something" other than TV Server?
    2. Did you intend to configure TV Server to use only 2 of your 3 tuners?

    Regards,
    mm

    So I am seeing the same issue. Basically if I am recording (or watching) one channel on the HDHR, TV Server has this error when trying to record/view another channel on another tuner and believes there are no channels available. If you look at the log at the start it thinks there are two free but then hits this error. Nothing else is using these (I brought a viewer up in HDHR S/W and it sees it fine).

    The telling lines are (I think):

    Hello and welcome twiseva :)

    Nothing else is using these (I brought a viewer up in HDHR S/W and it sees it fine).
    Well, either something is using the tuner, or something has left it in an inconsistent state.

    THINKS There are 2 free.
    That's only from TV Server's perspective. In other words, it means TV Server is not using those 2 tuners. It doesn't mean they're free. They could be in use by something other than TV Server.

    BUT Cannot tune.
    Sorry, "cannot" is not accurate. In theory TV Server could take control of the tuner, but when I wrote the code I made a deliberate design decision not to [take control]. I made that decision to ensure that TV Server would not disrupt other "things" that may be using the tuner.

    What happens if you reboot the PRIME?
    Do you run security software (particularly firewalls)?

    Hey, first thanks for super fast answer and insight into the underlying code.

    So I did try a reboot of the Prime and it DOES FIX THE ISSUE. As such, I am assuming as you mention above SOMETHING ELSE is leaving the HDHR in an inconsistent state. Not sure what but I'll try and reproduce and report back if I discover this.

    I also do have a firewall but seem to see nothing (easily visible) that causes issues.

    I do have other possible sources that might use the HDHR tuners:
    1. HDHR viewer (really just used for testing). I did a brief test and did not seem to cause the issue.
    2. PLEX -- HDHR application. Tried it but for now it could not tune (which doesn't bode well for it anyhow as there is a free tuner). I'll try and see if that might be it.

    I do have Microsoft Media Center installed but not running (that I am aware of). I'll see if that might be the cause also.

    Thanks again!

    Great. :)

    Okay. Please be aware that PRIME owners have previously reported that firewalls can cause problems if not appropriately configured. Something to keep an eye on.

    I do have other possible sources that might use the HDHR tuners:
    1. HDHR viewer (really just used for testing). I did a brief test and did not seem to cause the issue.
    2. PLEX -- HDHR application. Tried it but for now it could not tune (which doesn't bode well for it anyhow as there is a free tuner). I'll try and see if that might be it.

    I do have Microsoft Media Center installed but not running (that I am aware of). I'll see if that might be the cause also.
    If/when the problem occurs again, my advice would be to check the state of each tuner in the PRIME's web page.

    Really big thanks for the quick reply.

    I was trying to fix the issue, changing some settings here and there -- next thing I know, I ran into a familiar tvservice error. I didn't want to bug you about it, so I went ahead and did a complete uninstall and reinstalled everything again, importing previous settings -- didn't take too long. It did the trick, and now I can use all three tuners concurrently again.

    I uploaded the log of the tvservice error. Last time I ran into it, I was forced to uninstall everything as well :/

    Also, I'm not sure if you have the same tuner (HDHR3), but I'm sure you know way more than I do as far as configuring the TV-server settings. The total number of IPTV cards should be 3 for my specific device, right? From there, each individual tuner can only decode 1 channel simultaneously, correct? I uploaded some snips of the settings.

    That usually means your computer's name or IP address changed. All is explained in this wiki page:
    http://wiki.team-mediaportal.com/1_...figuration_Fails_To_Start_-_get_Cards()_error

    Also, I'm not sure if you have the same tuner (HDHR3)...
    CableCARDs and CableCARD tuners are only used in America. I reside in New Zealand, so a PRIME would be useless to me. :)

    The total number of IPTV cards should be 3 for my specific device, right?
    The number of IPTV cards is irrelevant unless you receive IPTV (ie. TV from your internet service provider). I'm guessing you don't receive IPTV. Therefore you could set the number of IPTV cards to any value and it wouldn't make any difference.

    From there, each individual tuner can only decode 1 channel simultaneously, correct?
    Yes, correct.

    Based on these questions and things I saw in your earlier log files, I wonder whether you actually found and followed the CableCARD tuner setup guide?

    I have an HDHomeRun Prime. I'm having issues using more than one card simultaneously (i.e., recording a channel and trying to play one at the same time). I'm getting the error, "no free card available" whenever I try to play a channel when a recording is already taking place; or whenever I'm playing a channel and trying to record one. In a previous forum conversation with mm1352000, I noted how I imported an old setup, and all three tuners were working perfectly and simultaneously -- but I believe I overwrote that configuration with a new one after the issue arose, leaving me with a choice of starting over again or trying to fix the issue at hand. In any case, for future reference, I was wondering if anyone could help me get it sorted it out.

    I've gone through the initial recommended setup posted on this forum -- double-checked everything: three tuners with a cam limit of one -- epg disabled, stop card enabled; channels scanned and mapped to all three tuners; DVB EPG grabbing disabled. I've also done the whole stop/start tvservice thing, unplugging and replugging the power to the Prime just to be sure it's not the device.

    I'll upload some screenshots so you could double check everything.

    Just to be sure, I only need to scan for channels on one tuner, correct? From there, I can map those channels to all three tuners?

    Big thanks for any help :)

    @mm1352000 might know more, but for me it works as this:
    Scan for channels on one tuner only
    Take results form that turner and map those channels to the other tuners

    It should then work. I know you have posted that you have done these things already so i am a bit confused too, but yes you only scan on one and map to the others.
