It's a satellite one. No matter if I watch channels or stream videos from NAS drive, it freezes.

Yes, I've tried OpenATV 6.0, the latest nightly build image.

I guess I have to mention that whenever I flash an image, in the log window I get: Could not read CA. Try upgrading rescue loader to the newest one. I tried upgrading it with "update-rescue -v", downloaded the latest rescue bin from dreamboxupdate and flashed it, still "could not read CA".

Is it possible that the security chip is broken or not soldered properly to the board?
