EPG grabbing while & timeshifting is activated
EPG grabbing is activated for all tv channels and all DVB sources.

I get the EPG from DVB-T and the first DVB-S card. The problem is the idle grabber never tries to grab to EPG for the channels on the second DVB-S tuner. When i tune to a channel there, the timeshift grabber gets the info.

Do i have to enable something to get it to work for the second DVB-S card?
