I guess the correct term would be "artifacts"? I can see the video but here and there across the screen are small "boxes".
What is the CPU load during that time? The host CPU transfers the data into the shared memory on the card, so anything below 80-90% load indicates another problem.
This is what puzzles me. The CPU load is only about 10%
Have a look at the hdtsplay-demo in the hdshm3-folder. It is a simple demo that plays back TS files over the DeCypher. If that works, your basic driver setup (+ the HW) is OK, and something in the vdr (or the patches) itself is wrong.
Thanks, I will try this.
