So I received my replacement card from DC (thanks for the speedy service!). Alas, I am getting the same problem (analog plays fine, Digital crashes almost immediately).
At least now I know, it is not a hardware issue. So I started to try all the variation I could think of.
I went to the DVICO website, and they recommended a particular driver for NVidia cards, so I downloaded that. No change.
I changed decoder from DxVA to regular. That increased the time to crash from about .5 sec to about 3 sec. Hmmm, maybe IRQ issues? So I check IRQ and it is not sharing the IRQ (19) except with itself (BDA and WDM). So that looks okay.
Next I check my BIOS settings. I tried bunch of things, but two things seems to cause noticeable differences; PCI Delay Transaction (set to Enabled) and PCI Latency Timer (increased from 32 to 64 then to 128). With these changes, I can watch a digital channel for about 15 sec (with 64) or up to 30 sec (with 128) before it crashes.
Which leads me to conclude that there is some sort of PCI transaction issues with this card's driver and when there is a conflict, it crashes.
Now, I have NO IDEA how to resolve this issue. I can only increase the PCI Latency Timer so much, and it still crashes.
Does anyone have any idea what is wrong with my system?
