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
or:
2) Use Technisat Driver Version: 1.1

Option 1 did it for me.

success

Option 1 works. My latency graph looks totally different

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.
