Especially in an multicard system this behaviour breaks all
other concurrently recordings too!
Long time a ago, the DVB-firmware+drivers were so instable, unreliable
that a "data stream broken" always means:
Driver problem, nothing works any more, only reloading drivers
or rebooting solves the problem.
That's not true any more IMHO.
Driver and Firmware developer(s) had(ve) done a good job (thanks!)
so -at least here- data stream broken is meanwhile mostly caused
by bad weather or Highdefinition boradcasts.
AFAIK, rebooting my box, will (usually) not move away the clouds,
but switching away from the HD channel will help.
The handling of "data stream broken" occurs too if the
channel turns on it's encryption. That too leads to the
above race condition.
If it is impossible to "just ignore" data stzream broken,
the restart might use 4 levels:
- Reload the driver+firmware of the failing card only
- Reload drivers+firmware of all cards
- Reboot (warmstart) the box
- Coldstart the box by using poweroff and wake up after 10sec.
