    Hi

    Looks like the problem is with PMT:

    2010-12-01 07:27:13.922267 [(18)]: WaitForPMT: Timed out waiting for PMT after 10,0015721 seconds. Increase the PMT timeout value?
    Support for DigitalDevices cards like yours is still quite new. I recommend that you read (and ask for support) on this thread. I think that you need to use specific drivers for stability. morpheus_xx is the expert...

    I just tested on Mediaportal 1.1.2 with the DigitalDevices build from morpheus_xx. No problem there.

    So it is either a problem introduced with new code in 1.2.0 (I remember something on the PMT handling was changed) or the DigitalDevices handling needs to be adopted to the new code in 1.2.0. I'm still seeing the error described on the first post with the latest 1.2.0 builds. Any help on how to get it working again on 1.2.0 SVN is appreciated.

    I'm not sure that the Digital Devices patch for the latest drivers has made it into SVN yet (see issue 3208 - not yet resolved). As I understand it there was a problem with detecting the CI because the capture filter name had changed... or something like that. Anyhow, if the change isn't in SVN and you're using the latest driver then that would explain why 1.1.2 + patch works and 1.2.0 SVN doesn't. You'll have to either check the SVN log (would do it myself but I'm not at home - sorry) or ask morpheus_xx about that one.

    You mentioned PMT processing changes - as I recall there was one. Would be relatively easy to check if that is the cause. Simply take a copy of your SVN head code and then revert it to the revision before the change. For testing it should be sufficient to build the TVLibrary.dll, however I'm not sure of the impact of other code changes since the PMT change. You may also need TvLibrary.Interfaces.dll and TVPlugin.dll (and more???)...

    Just to let you know: morpheus_xx pointed me into the right direction in the other thread:
    Go to SetupTv, to your TV card, click "Edit..." and change the radiobutton from "pause..." to "stop...".

    The remaining question is, whether there is a bug in the new code preventing DD cards to work in pause mode or whether it would require specific code for DD to make it working or whether the card does not support this feature in general.

    Thanks for sharing the solution :)

    That is not a code issue. It is up to the driver to support that function. If it doesn't support it then there is nothing that the MediaPortal team can do. Upgrading the drivers *might* help (the driver developer might fix bugs or change something that allows support for pausing the graph in later versions), but this is not guaranteed. The only thing you can really do is to try to contact DigitalDevices support and tell them that their driver doesn't support "pausing the graph".

    Thanks once again for posting the solution!
