I do not have a CAM.
Just two (old) DVB-S cards.

It has not been very bad lately, I had only only 10 ARM resets

Jul  1 03:03:34 vdr kernel: dvb: ARM RESET
Jul  4 06:17:03 vdr kernel: dvb: ARM RESET
Jul  6 23:35:50 vdr kernel: dvb: ARM RESET

Jul 18 00:01:20 vdr kernel: dvb: ARM RESET
Jul 21 22:30:26 vdr kernel: dvb: ARM RESET


and only 15 VDR emergency exits

since July 1st. 

I believe that recent driver versions (I'm using the CVS version 
from July 22nd with Klaus' 2 patches) are much better than before.


However, I am still getting MANY channel nn not sync'ed errors:
