    I have a problem with TV stuttering. Every 10-15 seconds I get 0.5 second frame freeze. Everything else works fine. After long research I suspect it could be my PCI latency. I have readings in DPC latency tool like on attached picture.

    I tried many tricks including:
    - changing PCI slot;
    - changing PCI latency with PCI latency tool;
    - some settings in bios;

    Nothing helps. I know the problem is not related with:
    - GPU - it plays everything fine including 1080p;
    - codecs - I tried very different settings;
    - CPU - 20-25% workload during SD TV;

    Could someone check the diagram with DPC tool. Is it the same with you?
    I suspect it could be drivers/settings issue, but I have no idea what it is. Chipset, BIOS, DVB card, CAM???

    Hi kesar,

    i've had the same problem and a similar system. Try:

    1) BIOS Option: Disable C1E Stepping
    Enable Cool&Quiet
    2) Use Technisat Driver Version: 1.1

    Option 1 did it for me.

    success :D

    Option 1 works. My latency graph looks totally different :D

    Thanks a lot, Nessix. I owe you - if I can help you in future with anything, just give me a signal

    Small correction: options 1 & 2 combined work. The new drivers are useless.
