I look into igalan error.log and Isee that we have the same error. Here I found a description of it. Hope this help.

    I don't know what error you're referring, but whatever it is, it only affects the HVR-900, but not the PVR-350; so it doesn't look like DirectX could be the problem (because the same DirectX engine is used for both tuners, isn't it?).

    I posted the error here,
    you can also find it in your mediaportal\log directory, filename =error.log.
    I agree with you, the error only affects HVR-900, so directx should not be related, but it's the only error I can find in our logs and it happens immediately after resume from hibernation.

    Hi,
    This error "D3DERR_DEVICELOST" (going off) from hibernating or suspend it's not causing any harm, MediaPortal can handle it & recovers from it.

    Regards

    Bug update
    In my country there are also some radio transmitting in DVB-T, so I had the idea to rerun the test using myradio.

    I followed these steps:

    1 switch on the computer
    2 enter in mediaportal and remain in the main menu.
    3 put the computer in standby
    4 exit from stanby, mediaportal appear correctly in main menu
    5 enter in myradio and tune one of the DVB-T radio channel

    result:
    Audio stutter

    If igalan can confirm it we can exclude a bug in the TV module and think to something related to the driver management.

    infinityloop said:
    this idicates that the application is not able to release the hook before hibernate correctly or during the initialisation of the TV-Card after hibernate something goes wrong.
    That would explain this behaviour, too.

    I tested the new version of the quartz.dll and the stuttering is gone. (Hauppauge DVB-T Stick).

    I've read the description on the KB but that does not seem related to the same issue (stuttering after hibernation/suspend). Anyway I will test it today and post back, thanks! :)

    Dear Morpheus_xx, I still assume that the issue is not due to hardware problems. In the beginning of my search I thought, I would need to dig into the registry, but eventually found out that GraphStudio can in principle also change the merit of decoders. As a first step I attempted to alter the Microsoft DTV-DVD A/V Decoders, but...
