Hi,
This patch is for vdr users's which have several cards.
He changes the device selection, by adding two factors in the 'impact' choice :
- prefering a already tuned device
- the last usage time of device
So, all devices are used and zapping time is reduce.
Works better when eitscanner is disable.
Regards,
JLac
