Tvheadend

Hi,

I am running the latest kodibuntu with tvheadend (package installed is tvheadend 3.4.28~geb79aee~trusty) on a zbox ci320 (with Intel(R) Celeron(R) CPU N2930 @ 1.83GHz). Connected is a usb stick for cable: PCTV Systems PCTV 520e, firmware is in place.

I am having severe troubles with "continuity counter error", either image or sound are interrupted constantly.

The strange thing is: if the system is under (heavy) load, the errors are almost gone!

First I thought that the cpu scaling was causing the problem but I was wrong. Now, if I start four jobs (md5sum /dev/zero) to put the cpu under load, the errors are almost gone. As soon as I kill these jobs the image / sound is scrambeled.

Any ideas?
