Thanks for answering.
No, I'm not compressing the video signal. No configuration RAID.
Flicker is present in "preview" the 1080i video signal. When recording the video signal the flickering effect is also present.
I use sata drives without problems.
May influence the speed of the hard drive in "preview" of the video signal?..
If, As you say sounds like a data processing problem. But where?…
Thanks…
