I have not yet cable comfortably available so I can not do much tests, but I will try some time later. How will such corruption manifest itself? I saw on some DVB-T STB some artifacts, square areas affected when signal was weaker or disturbed, but could this be somehow distinguished? I will look at streamdev usage and report when anything interesting will be found, given some prerequisites are met for such test... > If you do get corruptions you can try forcing hw pidfiltering by > adding "-m dvb-usb-init.force_pid_filter_usage=1" to webcamd_flags > in rc.conf and see if that helps.
