VDR doesn't "try to get data by restarting". When a recording is active,
and there is no data received for a certain time, VDR assumes that there
is something wrong with the driver/firmware/whatever and initiates a reload
of the driver (actually the surrounding wrapper script is supposed to do
this, so VDR just exists with a specific return value).

When VDR is started, it waits until all CAMs are ready, so that any
timer for an encrypted channel could start immediately.
