> I don't yet know if this patch is the cause, but I have a setup I am working on which has a FusionHDTV7 dual express and after it
> has been running for a few days, vdr seems to loose contact with the second tunner. When selecting other channels using vdradmin and
> then going back to the channel it had been left on for awhile, I get the xine no signal screen. Switching to any other channel
> works. Using femon I switch tunners while on the channel that no longer works and it starts working. I can go to any channel and
> swith between the tunners and only get video on the first tunner. The problem may be triggered by recording but sure. The amount of

> First I thought it was the driver crashing. So I tried restarting vdr, but not the drivers and that got the second tunner back.

>> 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.
